Excuse me? What do you think you're doing?

The other morning I was upstairs going to the bathroom.  Things were awfully quiet downstairs.  All moms know that unless it is naptime, quiet = trouble.  I promptly bounded down the stairs, my eyes scanning the living area until I found who I was looking for.

"On the table with my cell phone?  And just who do you think you're calling?"

I'm a little afraid for when he's a teenager.  I can hear the conversation now, "In my car with the keys during the middle of the night?  And just where do you think you're going?"
