I recently found out I hate chinese language. I don't hate the whole thing but when I hear it, I get really annoyed. I was sitting in front of a group of Chinese people in the library and I had to keep my headphones on because I would get too annoyed to study..

It could be that they don't even realize they are being offensive because it's not something that is offensive in their culture.
Accents annoy me more than anything. I don't particularly like heavy country accents or New York accents.
It's so irritating!!
