Pet peeve - everybody has one

If I had to narrow it down to one :-) I'd have to choose ignorant people. Not just any ignorant person, but the ones who you know are smart enough to understand and just too lazy or flippant to want to figure it out.

I can't stand someone snoring while sleeping in a public transportation when riding a bus, especially if that person happens to sit beside me! I don't know why, it irritates me that much. Another pet peeve is to hear someone laugh loudly while inside the private library - supposedly people who came to the place to study or read should remain silent so as not to disturb other people.
