Hobbies for teenage girls?

So it's the summer and i get pretty bored. My parents don't allow me to go to friends houses, or for friends to come here. I can't hangout at the mall or the movies, or anything. So i'm pretty much stuck at home. I have a pool outside, but my parents don't allow me to go there when they aren't home. I stuck at all sports, no I am not fat, just one of those nerdy, glasses chicks:P I thought about volunteering.. But I don't like kids. Animals are okay. I am terrible at arts and crafts. I have a dog, but all he does is sleep, no he's not fat either xD, just old! So yeah, thanks(:
