I don't try to make friends, because I'm typically very detached from the world around me and inattentive to others. Everyone blends together to me. (For example, in this place, I can't really tell one person apart from the next just yet) Even if I do notice people I like, it takes me a long time of being in the same social setting. And that doesn't mean I'll approach them, because I most likely won't. I'm too awkward for that and I don't have the patience to get through all that small talk. Most conversations with people go nowhere, and most relationships are just casual, talk every now and then, sorts of things. I don't consider that a real friendship. Friendship to me is a very big deal.
If someone's going to be my friend, they'll have to work really hard in the beginning. I'll kick in once I start realizing that you're important to me. And trust me, that takes me a while to do. You could think we're the best of friends, and I'll still think of you as an acquaintance. But once I stop thinking that, I'll start putting forth loads of effort and work. Sometimes I'll come to you. But I either have to be in a random mood of confidence or you have to stand out a lot to me.
The only reason I've made friends is because my personality on the internet tends to attract the attention of others. They start speaking to me, and I engage them, not really thinking much of it. Eventually, a connection forms. But that hasn't happened in years. I mostly just wait for people to come to me.
