So I was in a library at my university trying to finish a fairly large term paper that was due the next day. Needless to say, I was stressed. I chose this particular library because it's out of the way and is probably the quietest library on campus.

I had been there for about an hour when I hear a pretty loud belch from a few seats away. "Kinda rude", I think to myself, but I continue on with my work. Maybe 20 seconds later I hear another loud, obnoxious burp. This continues for probably 10 minutes. Every 10-30 seconds this guy 10 feet away from me lets out of these sonic boom burps that ricochet off the walls and shelves in the library. I look around and make eye contact with a girl who is sitting even closer to him. She has a pleading look in her eye that is telling me I HAVE to say something. I decide its time to take action.

I get up and go over to this guy and stand next to him and say, "excuse me". He has headphones in which makes it much more awkward because now I have to wait for him to notice me and take the headphones out. I say "excuse me" again a bit louder, and he pulls them out. "Hey man, do you think you could keep it down?" I say in the most non-confrontational tone I can muster. His response still haunts me... " I have a disease. I can't control it." Oh shit. I must have said sorry ten times as I back-pedalled away.

AITA?

I mean, if he knows he has a condition that causes him to be loud and disruptive, he could excuse himself from the library until the episode passes... right??

Or should I have just kept my mouth shut?
