... I go to the store to get him Ben & Jerry's Ice Cream. Fortunately it coincided with a normal shopping trip this time!
#3 has a friend (who happens to be a girl, but DON'T call her his girl-friend) who frequently comes to the house straight from school with him. She is in his class, and was last year also. She and #3 have become best buddies since Alec moved away. It actually works out well for her to come over as she and #3 do their homework together. This is the only time I don't have to fight #3 to do it.
#2 is a different story. He had math today. The first time he refused to do it, we had words. The second time he refused, he stood against the wall with his nose touching it and not moving for 15 minutes. After that he did the homework. He hasn't learned yet that there is no way he can win these arguments with me.
