Karate Kid

Rivka (5): I wanna take Karate

Me: Why?

Rivka: Because I'm good at hurting people.

Me: What?

Rivka: You know, like kicking (she kicks the air a couple of times for good measure)

Me: You don't learn karate to hurt people. You do it to exercise.

Rivka: No, you learn it in case someone doesn't do something you want them to do.
