I think I might be tired

This is a conversation from last night:

Matt (holding a sleeping Baby Girl): I want to put her down, but I think she'll wake up.
Me: I don't know what that word means.
Matt: What?
Me: Uhhh... I mean, yeah put her down.

In explanation, I answered his question with what I was looking at (a word on a photography blog) instead of the answer I meant to give him. Have you ever been able to think about one thing while talking about another? I can... usually.

I think those days may be over for me.
