Ah the pressure! I'll think on it. When I turn 30, I'm pretty sure that I'll just go drink enough to not remember it
I'm a little insane and get a kick out of the bizzare so while I'm thinking, here's a couple of things I've done.
1. Dress up (as dressy as possible and then add too much jewelry) add 1 tiara. Grab a fancy table cloth, battery operated "candles", a single rose in a vase, and an equally dressy person(s). Proceed to the fast-food restaraunt of your choice and enjoy an lovely, "candle" lit dinner. You can even bring wine glasses for your diet soda.
2. **Warning** this is not for everyone!!!! Have an adult scavenger hunt with a group of girls. Nothing freaks men out more than having a group of women charging into an adult store looking for some bizzare toy or video
3. Ice blocking. If you haven't done this before, it's a blast and will not only keep you moving, but makes you feel incredibly young if it doesn't kill you. Each participating party must purchase their own block of ice. Proceed to a steep, grassy hill. Go to the top of the hill, place a small blanket or coat on top of your block of ice to keep your tush from freezing, then sit on it. Now slide down the hill on your block of ice. Great fun!
