When you're dressed up like a princess, it's easier to act like one. If a tree had apples last year, don't expect pears this year. One drop of black paint from the brush clouds the whole cup of water. You can't be everyone's best friend. A snow day is more fun than a vacation day.
All libraries smell the same.
If you want someone to listen to you, whisper it. Sometimes you have to take the test before you've finished studying. Silence can be an answer. Ask where things come from. If you throw a ball at someone, they'll probably throw it back.
