I've had lots of girls who've came after me and I could have went on a date with any one of them...but I'm just not interested in that kind of thing. The first few times I had to tell a girl off were pretty difficult, but I'm accustomed to it now. Strange enough, at my new school I was asked if I wanted to "do something" with them (hint hint) by one girl (I was only at that school for two weeks). I try to be as unavailable as possible, and it has worked seeing as I only get a few girls interested in me per year....but it's not perfect. I'm a nice guy and I can see why they're interested in me. I'm just not interested in THEM. I've only made a girl cry once when I told her off and she was just way over sensitive. Once I explain the situation to them, most of them understand and there are no hard feelings between us. The one that cried was just too attached. She quickly forgave me and said she understood soon afterward.
I guess it's just not "normal" to want to stay single and not even go on a date, but I really don't care. I am who I am and I just don't want to do those things. I can't wait till I get out of school because at school you're FORCED to be with that person every day and they could possibly become interested. But in real life, you can just walk away and you can better show that you're not interested.
