People who don't park straight

Call waiting - I'm with you there ChocolatePuppy

Yes, to a certain extent spelling mistakes bother me. After I post, I always go back to read and fix any mistakes. Dictionary.com is my best friend.

Shortcuts......u instead of you and r instead of are. Don't mind things like BTW and LMAO....

Cashiers that don't pay attention. I was in the store the other day and two cashiers were yelling back and forth about their upcoming evening "what should I wear" and all that crap. She almost gave me the wrong change back.

People at work who don't clean up after themselves. They leave dirty dishes in the sink. How much effort does it take to put a mug in the dishwasher??

Dog owners who refuse to pick up.
people who call you, with no intention of actually talking to you.

Boy Cali, do I ever hear you there. I was speaking to someone a long time ago and all they ever did was talk to their pets. Drove me crazy!! Thank God for call display!

I'm sure there is more but for Cali's sake, I will remain happy.
