What pissed you off today?

[Princess]

My sister pissed me off today.

Now keeping in mind it's mothers day and I have had plans with my mother for at least a week to take her out to lunch and spend some time with her. My sister knows this..Today I went to pick up Mom for our lunch and my sister calls. Mom picks up and tells her we are on our way out of the door to lunch. My sister then hangs up on my Mom, a few minutes later walks through the door and throws a hissy fit because she had been planning to cook my mother lunch. Why would she make that plan knowing there were other plans in place? Instead of making a big deal about it I offered to take her out with us as my treat, she threw her hands in the air and walked into her room and sulked instead.

I am told she stayed in there all day, and only came out for dinner.

How rude! Luckily my mother is an understanding woman and she didn't think too much on it. But come on..its mothers day, give it a break!
