You can't trust dogs to watch your food. Reading what people write on desks can teach you a lot. Don't sneeze when someone is cutting your hair. Puppies still have bad breath even after eating a tic-tac. Never hold a dustbuster and a cat at the same time.
School lunches stick to the wall.
You can't hide a piece of broccoli in a glass of milk. Don't wear polka-dot underwear under white shorts. The best place to be when you are sad is in Grandma's lap. It's hard to unlearn a bad word. It's easier to see the mistakes on someone else's paper.
