I love ol' sneaky snake

My daughter thinks she's sneaky.  After 21 years of being caught repeatedly at her "hijinks" she still thinks she's sneaky.  You think she'd realize that I'm onto her but for some reason she's not picked up on that yet.  First of all she has this lie face.  Everytime she's lying she makes this face.  I wish I could describe it.  It's a don't look at me, I'm up to something kind of face.  She doesn't seem to realize she's making it so she thinks I'm a mind reader.  Well I am and I know what you are thinking and doing right now and that is so gross and your hand does not belong there.  See I am psychic...I knew exactly what you were doing.
