They always decide ahead of time what they're going to answer. Grownups make mistakes, but they won't admit them. They always pretend that they weren't mistakes at all or that somebody else made them. Grownups interrupt children all the time and think nothing of it. If a child interrupts a grownup, he gets a scolding or something worse.
Grownups never understand how much children want a certain thing a certain color or shape or size.
Sometimes grownups punish children unfairly. It isn't right if you've done just some little thing wrong and grownups take away something that means an awful lot to you. Other times you can do something really bad and they say they're going to punish you, but they don't. You never know, and you ought to know. Grownups are always talking about what they did and what they knew when they were 10 years old but they never try to think what it's like to be 10 years old right now.
