That tends to wear off as they get older, however. Not the liking school part, but the wanting to go back part. :o)
The thing that drives me crazy is the dissatisfaction angle. Can't wait to go to school, can't wait to get out of school, can't wait to...you name it. But, that is part of childhood. Every new stage brings new challenges. It sure keeps us humble!
I am very happy with them though. They are the perfect kids for us.
