"He who marches out of step hears another drum." ~ Ken Kesey
My son has a similar problem, and in fact also had trouble with his friends being available for a party. So, when he was about seven, I made up a form from the Department of Birthdays, officially changing his to June 23, when the weather is nicer, his friends are available, and he didn't have it "watered down"
thanks guys...turning 29 was a lot better seeing you guys wish me a happy birthday
