He is cute, I am not

Today while playing on the floor with his trucks Finn Said " Mommy I enjoy interaction!" The thing is someone on the TV just said that and he was repeating it but it cracked us up. It is true, he enjoys interaction and is always trying to get us to play with him.
A couple of days ago we were in the car coming back from the mall and I was feeling a bit defeated. We had gotten a bill for medical stuff that happened last year and should have been covered by the insurance that Kate had at the time but wasn't. It was the latest in pile of bills that come when you think you might finally be doing well. Anyway I was moody and quiet and trying to explain to Kate why while Finn asked question after question in the back seat. I told him to wait a minute while daddy was talking and he kept asking and asking. I snapped at him "Finn I need you to SHUT UP for 2 minutes!" and even before the words left my mouth I felt like an ass. Finn clammed right up, not saying another word for a minute and then saying to Kate, "Daddy says shut up Finn." I turned and to him and told him I was very sorry for saying that, I was wrong and should not have said that to him. He said "It's OK daddy." Later while we were driving he said "Sometimes daddy says no, and sometimes daddy says shut up." I wanted to cry, I know I will say and do terrible things but knowing that doesn't take the sting out of it when you have just done it.
