Love songs. If they make me so sad, why do I listen to them?

By sad, I mean this. And the explanation isn't short. I know that I have already said that I went to Homecoming alone and there, they played so slow dance songs. They made me sad, because I had no date, and eventually danced two of them with G. But, whenever I hear one, I think of love, which is something that I don't think I will never have.
I have had so many crushes over the course of my 15 years of living, it is sad. There is a really good description of crushes in a book I once read. You like someone and the other person doesn't like you. And, by the time they are actually paying any attention to you, you have moved on. So, I was just on the computer, partially listening to music and doing my spanish homework at the same time, when a song came up. It is by They Might Be Giants and is called "Another First Kiss" Considering that I have never been kissed, the song has always generally depressed me. But, I don't know why, but it seemed to weigh just a bit more heavely today. I know that it wasn't because of any "im"ing I did, and hopefully, I will be able to think up of why by tomorrow. Anyway, my mood is really strange, so I'm going to go and practice, CSpiccologurl
