Tough guy

I had another "bad mom" moment yesterday.  It was my turn to teach Bostons preschool yesterday, and when it got over I needed to help take something out to one of the other moms cars.  So I put Nixon in the house with some toys, but since the little ladies were leaving the door kept getting opened and Nixon tried to make a run for it.  He ended up meeting our doormat with his face!  Poor little guy looks like he got into a fight :(  I feel so bad!
