Wheee...I have some pet peeves.
I hate it when people misuse acronyms, particularly when people are redundant and say things like "ATM machine." ATM stands for Automatic Teller Machine, so you don't need to add "Machine" to the end. That's why there's an "M." Similiarly people saying "PIN number." PIN = Personal Identification Number.
People smoking in expensive or nice cars. Why not just take some art and spit on it? Considering what you're doing to the value of the car, you might as well.
I hate driving. All forms. Driving is a huge burden to me, despite it's many benefits. (I don't mind when most other people drive, I just don't like doing it myself).
Adding to that, stupid and dangerous drivers give me mental breaks.
Busy work for school. ::daggers::
Intolerance or purposeful ignorance. Especially degrading others on the basis of race, religion, or sexual orientation. Generalizations usually upset me as well (which is funny, because this list is full of them).
Napoleon Dynamite.
People thinking you're beneath them because you live by standards. (i.e. I don't swear, so I must be naive. I don't drink, so I must be a stick in the mud, etc.)
Substituting religion for logic in places where it is inappropiate and imposing on the rights of others to use religious justification for action.
When foods spell it "creme" and then expect you to pronounce it "cream." "Creme" is French, if you didn't want it pronounced the French way, spell it "Cream." (creme savors, raspberry creme soda, etc. Look at the package next time.)
People feeling offended when you have a minor difference of opinion ("I loved that movie! What did you think?" "I didn't like it very much." "How could you not like it?" "The humour was too crude for my taste, I guess." "But it was a really good movie!" "I'm glad you enjoyed yourself, that's good for you." "You're stupid if you didn't like that movie." "Come again?" "I can't believe how dumb you are!" o.0 )
