Conversation with a 4 year old

I had just put Buddy down and called for Macey to come up stairs.  I know she doesn't like to be alone when I shower so I was calling her upstairs to let her know I was going to shower and code for bring your toys up to my room.  When she got to the top of the stairs this is how our conversation went:

Mommy:  Macey I'm going to take a super quick shower what are you going to do?

Macey:  Uh, babysit myself!

Mommy:  Okay, how are you going to do that?

Macey:  Well, don't answer the door or look out the window if anybody knocks on it.

Okay, I can't argue with that!  I'm thinking when she gets older she is going to out smart me on any conversations we have.
