If your parents let you watch PG-13 moVies. You should get :
The Love Guru
If they don't go to your local rental store and find some cool ones. If you're not too much of movie person, you should try to get paper, to drawing is a good way to use spare time, borrow a friends ipod or if you have your own buy some new songs you haven't heard of, or you like.
Or, you could go to Walmart or Target, Walmart has a clearence section that you have good deals on. I go on a 18 hour car ride, and I am on the way to Michigan, I use the same stuff each year. Poratable DVD player mostly. You should get some joy out of some of the clearance items.
I myself am eleven and it's hard to come onto Yahoo Answers and have it kid like. You have a lot of 'sex' questions. (gross)
