Everyone has them! Normal, everyday things that everyone else seems to do or say without even a second thought, but for whatever reason you find strange or can't stand! For example! I can't stand when people wish me "good luck" in matters of skill or preparation. If I'm going into an exam, I don't want your wish for good luck because (at least for me) luck has nothing to do with it. I either know the material or I don't! I prefer an encouragement like "do well on your exams" or even "kick some ass" - both of which are more directly related to my own preparation and performance during rather than simply getting lucky. Now, if luck is actually involved (like if I'm in Vegas and am about to hit the tables), then "good luck" is totally acceptable! I also, for some reason, just don't like the phrase "rule of thumb." I dunno why exactly, it just kind of bugs me. What are some of the things that YOU find weird or annoying that most other people seem to just do?
