I have MANY but I cant think of them all now... so:

1. When someone does something "bad" and you do the same thing back, its OK for them to do it, but when you do it... it turns bad. Did that make sense?

2. When people constantly snap gum, {because I cant do it}

3. People who chew like cows

4. Slow typers

5. People who hit their dogs.

6. When someone sees that you are talking and they continually call your name until you turn around.

7. When people go about 10 miles below the speed limit.

There are a ton more... I just cant think of them. I think I get a new pet peeve every day.
