Just a quick thought.

It's fun teaching, observing children and reminiscing what it was like to be that age.

Remember what it was like to want to run everywhere you went. Run to turn in a worksheet at school. Run when you see your parents to take you home. Run to the water fountain.

Funny. I'd probably look crazy if I did that now, but it's funny to watch my carefree students (they have a baffling amount of energy. Seriously. I get tired just watching them).
