Well, since you asked or didn't..
Here is what drives me insane in my membrane:
I am really bothered by people who walk around with obvious black or whiteheads on their face. Pick it. Please.
I get really annoyed when people overly touch their food. My sister not only takes apart her sandwich, but touches everything a ton and I have even seen some people smear catsup with their finger.
I don't like the overuse of apostrophes.. especially in store signs! The "excessive use of quotation marks" is also annoying!
Littering really irks me. I feel like it's just laziness in many cases.
Another pet peeve is the sound of styrofoam rubbing against anything. It makes me cringe!
I get so annoyed when people don't tip. Really people, do you know what it's like to make $3.50 an hour? Do you really know what it's like to serve a random stranger's every whim for ranch dressing, more mr. pib and then more ranch dressing?
I hate when I hear "she didn't have enough money to go to school". She can take out a loan.
Why oh why oh why oh does it ever make sense to drive in the fast lane when you are clearly a slow lane kinda guy or gal?
Socks + sex never make sense.
Egg sandwiches. Possibly because they are often served with catsup or catchup or ketchup.
Why do old people think it's ok to say anything on their mind even when it's insanely offensive? That is so annoying.
I can't take it when someone doesn't follow the basic laws of the land in regards to taking turns in the line at McDonald's. I believe in karma, and you will be peeling off your own toenails in hell.
