I Hate People
I invited some chick in my class to my sweet 16 because I felt bad that no one seemed to like her. I discovered the reason for her unpopularity was not only that she was a bi**h, but a complete whore who was all over the guy I liked the whole time. When the party was near to being over, they decided to share their affections by making out in front of me. Did she know I liked him? A mentally incompetant turtle could tell I liked him. Now I can't stant looking at them without wanting to punch babies.
That sucks): I hate people too don't worry! Throw stuff at her.
I'm sorry to hear that; I've had the same situation happen to me but with one of my close friends. I've gotten over it, but keep in mind: would you want to date a guy who know you liked him but decided to make out with another girl in front of you at your own party? Don't give up hope, there are plenty of fish in the sea.
