I've spent most of my summer inside reading, listening to music, going online, working out, watching TV, cleaning everything in sight, knitting, memorizing pi, working on my summer homework for AP English, and wondering why we have such a long summer vacation anyway. I'm also taking a couple classes at community college, volunteering at the library, and occasionally babysitting for an incredibly annoying 5-year-old. I'd like to get a job, but it's next to impossible to find one in my town what with a) the recession, and b) our proximity to a college.
My NT sister spends her time playing Sims 2, hanging out with friends either at our house or theirs, at theater or dance camp, at the outdoor pool, shopping, and eating a ton of food.
I don't know what anyone else is doing. I think they spend a lot of time sleeping in, then hanging out with friends and playing outdoor sports.
