So, excuse my ignorance of many things American, but I'm guessing this means you turned 21? (it'd be 18 over here)
If I'm right, then happy 21st! And remember to spend twice the amount of time you spend on games on making yourself interesting to the other sex (if you're so inclined. ). That's a pretty decent rule of thumb, in my experience, and makes you feel a lot less guilty about gaming and such.
(But then maybe you're here professionally, in which case this doesn't count.)
