Jill: Well, because some kids are just mean. They think by calling you names that makes them cool. Let me tell you what real cool is. Real cool is feeling good about yourself and not worrying about what other people think.
Mark: What do you mean?
Jill: Well, let's use your father as an example. Your father does some things that some people might consider dorky. Like the time that he froze his tongue to the hammer, or the time that he glued his head to the table. But it doesn't bother him. You know why?
Mark: Why?
Jill: Because he feels good about who he is. And you should feel good about who you are.
Mark: I should?
Jill: Yeah. You are a great kid. You are so smart, and you're fun to be with. And you care about other people, right?
