The article I read is called Tasty Thursday it is about a teacher and her class baking for a random class in their school every Thursday
They didn’t do any research just baking goods for another class, they have found that the whole school gets excited on Thursdays in hope that they get the knock on the door with the tasty treats.
Yes, it is nice that the kids can be participating in such good works at such a young age they can see the joys and beauty in giving.
Another act of kindness I found was about tipping big and making a waiter do a double take. I picked it because some people get tired of their job and waiters have to deal with such rude people and the tip will show them they are appreciated.
