I know this sounds really mean, but let me explain. There is this girl, and let us call her Mary. She and i use to be really close, but of the last few months she has become extremely mean. I went to an event with my parents, and Mary and I had planned to hang out. I went up to mary and said,"Hey, Girl!" She just looked at me like i was a village idiot. Then, she started some stupid rumor about one of my friends (who will be at the party) saying my friend had sex with some guy. Which did not happen at all. While she is spreading this rumor, she tells everybody that I was the cause of the rumor. She also talks about way too many people and spreads way too many rumors. I just don't feel comfortable around her anymore. I know this is mean to univite her, but this is my birthday. We are going to a really expensive, nice resturant, and I don't want her there. See, I have 2 best friends, and one of them is in the hospital with maybe cancer. So, she probably isn't going, but my other best friend is coming to my birthday party. So, then I invited my other friend, the one who Mary started a rumor about her. Then, it is Mary and her best friend. I really want to univite Mary! The other problem is her best friend won't come, and she is nice. I don't know what to do! Help please!! I really need help!
