I have rediscovered why I can't go to dances by myself. I end up just wanting to cry.
It's just like high school. You go to a dance hoping to run into people you know and hoping to have a good time. None of your friends come. They don't dance. The only ones there are the popular people (who give you the cold shoulder when you try to talk to them) and the couples (whom a single girl definitely does not want to mess with). So you're left sitting at a table by yourself or leaning against a wall watching the people on the dance floor have a good time. You feel as though you're invisible, because no one will come talk to you, or even acknowlege you for more than a few seconds if you try to talk to them.
Why do I go to these things anyway?
