Ah to be 13 again... But anyway, here's a couple of ideas. For my 13th, my mother allowed me to ask 3 girlfriends to my "party", it really wasn't a party, but we'll get into that. She let me pick a movie, pick a restaurant, and the only interference I got from her was paying chauffeur and paying for the movies and the food. Sine my mother had never allowed me to go to the movies alone with friends before, or go out to eat alone with friends, this was a huge deal to me. So there's one idea. Here's another, once when I was about 13-14, my friend asked me to a slumber party, her mother has just started selling Avon or Mary Kay, I forget which, but what we had was a combo slumber/makeup/spa party, we got to have a ton of fun, try new makeup, and put this green gloppy gunk on each other's face. I think my Best Friend still has a few pics of us somewhere. It was a total blast, and something I think every teenage girl should experience.
