In boot camp when they start assigning details, they're gonna ask you, "Is anyone here artistic?" Actually, they're gonna say "autistic" but make it sound like artistic. Do not raise your hand. They're going to make those people order rocks in the courtyard and arrange them all in the same color.
You should, however, do what I did: volunteer to do the flight/platoon/whatever you have in the Navy's laundry. You just take everybody's laundry down to the washers and dryers and you just sit there for hours, getting everything done. You can catch up on writing letters, reading and studying for your final exam, etc. It's usually you and another person. It's easy as shit because everyone has a laundry bag and in that laundry bag is a net bag for everyone's clothes. All you do is throw all those bags together in the washer, dump in some detergent, and that's it. It's not like you have to touch anyone else's laundry or anything. There will also be other people from other flights doing their laundry, so you can actually talk to someone. We'd always flirt with the girls from the other flights. A few people got blow jobs in there. Just don't get caught.
While everyone was busy cleaning up the barracks and scrubbing the floors with toothbrushes, we were sitting on our asses for hours with the laundry, just hanging out. No one could say anything about it because it had to get done and you couldn't leave it. It was cool.
Lord Foul is right. We had the Drum and Bugle Corps which played for all the marches and stuff, and they asked us if anyone plays drums or trumpet. I, fortunately, did when I was in high school, although only for like 6 months. They didn't give a shit. They got us after the first week, dragged us out of our old flights and put us all together again in a new one. Everyone else hates you, though, because you get all these special privileges like going to basketball games and performing at marches and parades and shit. We went to the Alamo Bowl I think while we were there. They'll call you pussies and faggots and shit, but you get to hang out, go to ballgames, eat real food and stuff while you're there. The only difference is that you have to go to practice like twice a week and that's it. I'm sure the rifle corps for the Navy is the same.
Basically, volunteer for anything that puts you by yourself, with a very small group of people, or away from all the instructors. Usually these tasks give you more freedom and you'll enjoy it more.
