Thanks everyone for replying. It caught me off guard. SHE was blocking a parking space unloading groceries and I try to inch in around the cart. She moved it a bit but when I bumped it she yelled at me. I wasn't going to say anything at all until she snapped at me and said I almost hit HER car.

Then I just let it fly and called her a *****. I was trying to be polite by not saying anything and she *****ed at me.

I have a hard time being *****ed at by a stranger. Who knows? Maybe she is bipolar too! lol
