Laura: I don't know what to do, Pa.
Charles: Well, then, just don't do anything. You didn't do anything wrong. There are a lot of funny notions born inside of us, Half-Pint, and one of the funniest is that we're supposed to hide the way we feel about others. Let me tell you something, everyone needs to feel that they're loved, needed, and cared about. Anyone who doesn't want to know that has something wrong with them.
Laura: (about Jason) What will he think of me?
Charles: Well, if he liked you then, I think he'll like you a lot more now. There's nothing bad that can come from telling someone how you feel.
Laura: I know what you're saying is true, Pa. But it was just such a terrible thing to do!
Charles: Oh, I know it was. I know it was. (kisses her)
Laura: I don't want to be a scientist anymore. I don't want to invent things that hurt people.
Charles: Well, it's not the inventions that hurt people. It's the people, and the way they use them. That's what hurts. Everything's going to be all right.
