Three Conversations with Charlie (Age 5) About Star Wars

My boy is awfully fond of Star Wars. In the same way that a koala is fond of eucalyptus. He thinks about it all the time and consumes it some form (book, stickers, Lego, prying Dad for more information) almost constantly. He's very intrigued by the Darth Vader - Obi Wan light saber battle because it's dramatically important and because it's too scary for him to watch so I need to describe it nearly every day.

HIM: Kate! I'm going to bonk you on the head! I'm going to strike you down!
ME: You can't bonk her, Charlie. If you strike your sister down, she will become more powerful than you could possibly imagine.
HIM: What?

HIM: Okay Kate, hold up the bat and I'll be the thrower.
HER: O-KAY!
HIM: And I'm going to strike you out!
ME: Careful, Charlie. If you strike her out, she will become more powerful than you could possibly imagine.

HIM: Dad, why does Obi-Wan say he will become more powerful if he gets killed?
ME: Well, he means his ghost will become powerful.
HIM: How can a ghost be powerful?
ME: He can talk to Luke once in a while. Give him advice. Be kind of a friend and helper.
HIM: Like a ghost helper?
ME: That's right.
HIM: Well, that's just stupid.
