crafty little guy!

Sawyer's new thing...learning to lie! These days when Sawyer gets in trouble he questions me. Not about why he is in trouble, but how I knew he was doing something wrong. I reply "I just know", or "mothers see everything". So then he asks me "Did you hear the door close? Did you see me on the monitor? Did you hear my footsteps?" It's like he is trying to get me to learn how to lie better so he can avoid getting caught next time. It's driving me crazy! Do other children do this?
