Praying. I can understand how annoying that is. Me and one of my classmates were preparing a fallacy to present to the rest of the class, they had to guess which one it was. I was having a great time trying to create something hard for them to guess, when she sucked all the life out of it complaining how hard it was, and how we should do a really easy one because she was bored. It was really annoying.
Doctor, I have major anxiety and paranoia, so I can definitely relate, though not on such a major scale.
