#4-swearing & #6(rude co-workers) bother me a lot. I'm not saying I don't curse but saying "F-ing this, and F-ing that...well, get a thesaurus and learn a word a day and stop being ignorant.
Actually, swearing is a habit...
#6--Well, you know some coworkers have 'issues' so they can't say hi...others never shut up (think Milton the Squirrely guy in
Office Space...)
