What’s Your Pet Peeve? Everybody Has Them, What’s Yours?

Every one has at least one pet peeve and some have many. A lot of mine are grammar related. My grandmother and aunt were both English teachers and I got away with nothing when it came to grammar.  My latest peeve is when I hear the word "anyways". It doesn't make sense. It's an adverb and adverbs can't be plural. Are you seeing what kind of hell my relatives created for me?  Another one is "left lane cruisers" when I'm on 94 or Highway 10.  Left lane is for passing. So, what are your pet peeves?
