Awww... Nassim!
First of all, Happy Birthday.
Second of all, I feel your pain. My birthday is notorious for falling during people's vacations. Ever since I was a kid...
I think it was worse when I wanted to really go out and celebrate my 21st Birthday in Sacramento. My birthday was on a Monday (blah!) and when I went to Sac on a Thursday, no one was available to hang out, or were under age. So yes, summer b-days can be a bummer sometime.
Again. Happy Birthday!
