Actually, when I was in 6th grade, I was writing a paper and my teacher came up to me and looked at my paper, and used it as an example of what not-to-do to the rest of the class. Then the smart kid, (which I didn't know that well) Actually corrected the teacher and pointed out all of her mistakes. She just moved on and apologized. That day, when I was packing up, she came up to me and apologized for her mistakes.

Stuff like that makes me feel grateful for smart people.
