April or Septemember... just not December, like now. See, I was born only three days after Christmas, so I would always get cheated of toys as a kid, and nobody is ever around to come to my birthday parties/get-together because they're with their own families or on holidays (December is the middle of summer holidays down here), often travelling.
I've had to celebrate my birthday up to one month before just so SOMEONE would come to my parties. It sucks.
I have a December birthday. Worst month for it. There is always snow (which i hate), and people often get you combo birthday/christmas gifts. If I could choose, I'd go with June, weather here is nice, but not overly hot yet.
