<human>: My school had a trip to the local pool club for the graduating class, which I'm in. Our pool club has a pool (obviously) and an ice rink, and I thought I would go ice skating with one of my friends so he could teach me how to. Turns out I'm horrible at ice skating so I say, "Fuck it, I'm going swimming." I brought a swimming suit on the trip just in case, but I didn't bring sunscreen. So I go swimming for about five hours, and return home with a sunburned back, which I expected, but it didn't hurt. Fast forward to tomorrow morning, and I literally could not put a shirt on. My shoulders and back were extremely burnt to the point where anything touching them feels like flames coming from Satan's asshole. I had a day off from school that day, so I chilled in bed and played Pokemon Blue, and forgot about all of the end-year exams I have in school. I don't know if you have had to take a test with your back feeling like it's on fire 24/7, but let me tell you I usually get an A+ or A on every test, but it was so hard to concentrate that I got a D. I also have to run a mile for P.E. tomorrow, and that's going to be hell. Probably going to buy ten aloe plants.

Summarize the given text in a few sentences.
<bot>: Didn't wear sunscreen to the pool, now I have to run a mile while my back and shoulders feel like Satan's asshole.
