I was laying on the sofa on my stomach the other day when Hannah came to sit on me...because that's what you do when your mom lays down...don'tcha know?
Hannah: Mom...I'm sitting on your bum bum.
Me: Is it a little bum or a big bum (always worried about my weight)
Hannah: It's a big one!
Joe: (running across the room to join in)
How's that for the ego?
