Pet Peeve

Okay, so most people would think that my biggest pet peeve would be something to do with grammar, but I rag on people about that unless they send me something in a text. Then I'm like "com'n everyone texts so fast these days, is it really shorter to say UR instead of your?" (don't even get me started on your vs. you're)
Anyway, no my biggest pet peeve is shopping carts!
Not that they're so bad themselves, I really appreciate the fact that I don't have to carry everything around at the grocery store. No it's when people leave them all over in the parking lot and don't return them to the store or designated return areas! It's the worst when I go to pull into a parking spot, and then halfway in, I have to pull back out or get out of my car because someone has left a cart in the spot!
Ugh, I hate it!
