A little long but a good story.
1675115234659.png

As she stood in front of her 5th grade class on the very first day of school, she told the children an untruth. Like most teachers, she looked at her students and said that she loved them all the same. However, that was impossible, because there in the front row, slumped in his seat, was a little boy named Teddy Stoddard.
Mrs. Thompson had watched Teddy the year before and noticed that he did not play well with the other children, that his clothes were messy and that he constantly needed a bath. In addition, Teddy could be unpleasant.
It got to the point where Mrs. Thompson would actually take delight in marking his papers with a broad red pen, making bold X's and then putting a big "F" at the top of his papers.
At the school where Mrs. Thompson taught, she was required to review each child's past records and she put Teddy's off until last. However, when she reviewed his file, she was in for a surprise.
Teddy's first grade teacher wrote, "Teddy is a bright child with a ready laugh. He does his work neatly and has good manners... he is a joy to be around.."
His second grade teacher wrote, "Teddy is an excellent student, well liked by his classmates, but he is troubled because his mother has a terminal illness and life at home must be a struggle."
His third grade teacher wrote, "His mother's death has been hard on him. He tries to do his best, but his father doesn't show much interest and his home life will soon affect him if some steps aren't taken."
Teddy's fourth grade teacher wrote, "Teddy is withdrawn and doesn't show much interest in school. He doesn't have many friends and he sometimes sleeps in class."
By now, Mrs. Thompson realized the problem and she was ashamed of herself. She felt even worse when her students brought her Christmas presents, wrapped in beautiful ribbons and bright paper, except for Teddy's. His present was clumsily wrapped in the heavy, brown paper That he got from a grocery bag Mrs. Thompson took pains to open it in the middle of the other presents. Some of the children started to laugh when she found a rhinestone bracelet with some of the stones missing, and a bottle that was one-quarter full of perfume.. But she stifled the children's laughter when she exclaimed how pretty the bracelet was, putting it on, and dabbing some of the perfume on her wrist. Teddy Stoddard stayed after school that day just long enough to say, "Mrs. Thompson, today you smelled just like my Mom used to." After the children left, she cried for at least an hour.
On that very day, she quit teaching reading, writing and arithmetic. Instead, she began to teach children. Mrs. Thompson paid particular attention to Teddy. As she worked with him, his mind seemed to come alive. The more she encouraged him, the faster he responded. By the end of the year, Teddy had become one of the smartest children in the class and, despite her lie that she would love all the children the same, Teddy became one of her "teacher's pets.."
A year later, she found a note under her door, from Teddy, telling* her that she was still the best teacher he ever had in his whole life.
Six years went by before she got another note from Teddy. He then wrote that he had finished high school, third in his class, and she was still the best teacher he ever had in life.
Four years after that, she got another letter, saying that while things had been tough at times, he'd stayed in school, had stuck with it, and would soon graduate from college with the highest of honors. He assured Mrs. Thompson that she was still the best and favorite teacher he had ever had in his whole life.
Then four more years passed and yet another letter came. This time he explained that after he got his bachelor's degree, he decided to go a little further. The letter explained that she was still the best and favorite teacher he ever had. But now his name was a little longer.... The letter was signed, Theodore F. Stoddard, MD.
The story does not end there. You see, there was yet another letter that spring. Teddy said he had met this girl and was going to be married. He explained that his father had died a couple of years ago and he was wondering if Mrs. Thompson might agree to sit at the wedding in the place that was usually reserved for the mother of the groom.
Of course, Mrs. Thompson did. And guess what? She wore that bracelet, the one with several rhinestones missing. Moreover, she made sure she was wearing the perfume that Teddy remembered his mother wearing on their last Christmas together.
They hugged each other, and Dr. Stoddard whispered in Mrs. Thompson's ear, "Thank you Mrs. Thompson for* believing in me. Thank you so much for making me feel important and showing me that I could make a difference."
Mrs. Thompson, with tears in her eyes, whispered back. She said, "Teddy, you have it all wrong. You were the one who taught me that I could make a difference. I didn't know how to teach until I met you."
(For you that don't know, Teddy Stoddard is the Dr. at Iowa Methodist Hospital in Des Moines that has the Stoddard Cancer Wing.)
Warm someone's heart today. . . pass this along. I love this story so very much, I cry every time I read it. Just try to make a difference in someone's life today? tomorrow? Just "do it".
Random acts of kindness, I think they call it?
"Believe in Angels, then return the favor."

What a heart warming story.
Looking at an issue from a different view point can dramatically change our approach the all thing we encounter.
 
Recently heard a nice story told by a teacher.

First thing one morning, she said to the class of primary school kids, 'Put you hand up if your parents gave you anything this morning.' No hands went up.

Then she said, 'Put your hand up if you had breakfast today.' All hands went up. 'Put your hand up if you had clean clothes to put on today'. Flurry of hands. 'Put your hand up if you slept in a nice warm bed last night.' Flurry of hands. 'Put your hand up if one of your parents brought you to school today.' Flurry of hands.

'Now, put your hand up if your parents gave you anything this morning.' All hands went up.

Just thinking out loud here...

Gear drive vs. chain drive cams:

Gears more consistent/accurate(?)
Horrendously expensive compared to chain setup.
Noisy.
More power loss(?)
No worry about chain stretch changing cam timing.
Better at high RPM(?)

Other benefits/drawbacks?

You can have a lot of slop & backlash in a series of gearwheels. Manufacturing tolerances plus wear. Harder to get rid of it than adjusting a chain.

Them gear drives look exquisite though.
 
They almost remind me of a Cat Diesel D346 engine I worked on a few of back in the day!

V-8 four overhead cams plus balancers all run off gears. Two gear trains, up the front for the left cams, up the rear for the right cams. The front set also ran the oil pump. All straight cut gears.

And being the cams only had four lobes each at cranking speed as each lobe went past full open the valve springs would cause the backlash in the gear trains to make them snap to close the backlash. Actually at idle and a bit above you could hear all the snapping noise!

Sounds like it was designed by Germans.

Honda had gear drive cams in race oriented versions of several of their motors. Lash and noise in the straight cut gears reduced by using a split gear with the two halves spring loaded against each other, it loads both front and rear sides of the meshing gear's teeth.
The RH gear in this pic has the spring loaded section.

Racers that remove them claim the motor sounds like a dry cluch Ducati at idle.
Looks like there'd be room for that 'tween the cylinders in an XS650 motor......... ;^)

As a Scottish starship engineer (Scotty) once said "...The more they overtake the plumbing, the easier it is to stop up the pipes." Keep it simple. Fewer moving parts = less friction = increased efficiency. We don't need to re-invent the wheel. We know they are round. (My apologies to the flat-earth, square wheel crowd.)
