Logic.

On Friday night, Ruby accidentally locked herself in the bathroom for the third time. HOWEVER, it is important to note that this is actually the first time she was able to let herself out without us having to take the door off its hinges. Woo hoo, Rubes!

After the incident, Cici and Ruby and I had the following conversation:

DADAM: Okay, girls, here’s the rule on locking the bathroom door: no locking the bathroom door.

CICI: Yes, no locking the bathroom door, unless I’m in there with Ruby.

DADAM: No – no locking the bathroom door at all.

CICI: But I know how to unlock it.

DADAM: Yes, but it’s a better idea not to lock it at all.

CICI: Why?

DADAM: Well, because what if you got stuck in there?

CICI: But I know how to unlock it.

DADAM: Yes, but what if the lock breaks? You could be stuck in there forever.

CICI: No, I wouldn’t. You’d just take the door off, like you did for Ruby.

DADAM: Yes, but what if we couldn’t get the door off?

CICI: Well, why would that happen?

DADAM: Well, suppose the hinges broke, or got stuck, or something. You’d be stuck in there forever. It happens, you know.

CICI: Well, we could make a ladder out of something and try to go out the window.

DADAM: Um, I wouldn’t advise that. So the rule is, no locking the bathroom door, if you’re a kid.

CICI: Okay. No locking the bathroom door if you’re a kid, or a grown-up.

DADAM: No, grown-ups can lock the door if they want.

CICI: Why?

DADAM: Well, because we know how to unlock it.

CICI: Oh. [pause] What if the lock breaks?
