I'm at a music festival when I decide to change my clothes. I want to do it in private so I head over to the showers into an individual cubicle. However, try as I might, I'm unable to remove the shirt I'm wearing. It seems to be stuck on my arms. I look at my watch to see it's 9.49pm and I know Metallica are on at 10pm. The more I seem to rush, the longer it seems to take.
