I have no defence for Adders 1, only vague excuse is they reside in Australia where said offspring was born, there are NO real teams she could align herself too except the teams of her parents.This is easy, go with it, if the worst happens you have years of feeding in what "pop" stars and "celebrities" you saw at The Amex, you can also register her as a Junior Seagull, start buying her the odd bit of trendy merchandise (oxymoron) her and there and remind her of "the rules", you support the club closest to where you were born.
(Other than to never darken NSCs door again etc - in my defence she only told me she supported Palace during the second trimester )
What a stupid bet, shouldn't your daughter be free to decide herself assuming she grows up liking football.
What happens in the event of a draw?!
If she only told you during the second trimester and you hadn't figured it out before then she can't be much of a palace/football fan.......
