I didn't have one, I'm still 16 though so i don't know if I'll regret it, but i don't think so, it's just another Birthday party, I've had a bunch lol. I had a celebration with my family still, a cake and all that, but no friends over or anything like that.
It's not as happy a day as it used to be though, it's the day Max died, so I'm not really in the party spirit.
