We know a couple where the guy is an atheist, his wife is Jewish and their son is Jewish. Their son just married a girl who is a Muslim, her Dad is a Muslim, and her Mother just converted to Christianity.
So, they are all going to the parents of the bride's place to celebrate Christmas this year!
Also, none of them believe in the Easter Bunny, or in putting all your eggs into one basket!
