Well...what just pushes you over the edge? My list (by no means complete)...
-- People who don't use their turn signal
-- People who can't spell common words or use even halfway proper English
-- "Greatest Ever" or "Worst Ever" lists
-- People who think that 3 or 4 cars can still go through the intersection after the light turns red
People who ''''' around on the job, then complain about having to work longer hours b/c the work isn't done...so they ''''' around some more and end up working Saturday and then complain even more.
Inconsistent applications of company policy - Person A can have off for a "mandatory Saturday" b/c he/she can't find a babysitter, but Person B can't come in 1 hour late (or work extra during the week to make up that time in advance) b/c he/she is working a 2nd job.
- when the radio begins to play the same songs over and over again....
- cellphones ringing or vibrating in the middle of an exam or lecture
- hmm... ear-splintering fire alarms @ 3 am in the morning. Gah!
People on the train who get up and head for the exit....knowing that the train won't make it to their stop for another 5-10 minutes. What are these people in such a hurry for? There's no prize for being the first one off, or in the first 10 - you're just being annoying. Sit your (tail) down and relax for another 5 minutes so I don't have to have my left shoulder repeatedly whacked by your overstuffed briefcase.
That, and people who go through the stuff you left behind at your house when you moved, figuring that they are entitled to have whatever they want. (And then are shocked when they get arrested by the cops for theft, because that stuff really isn't theirs - it's still mine.)
