I have one close friend whom I would call my best friend, though he's never acknowledged me in the same way, and often refers to his other friends as his "best friends". He always goes <3 when I've said something quirky, or when I start talking about snails, as if it's some cute thing I do, when realistically it's quite a deep passion and not just a mild amusement.
I think that a major thing which sets us apart is sex, he talks about it sometimes and while I say it's okay to talk about it, I can't say that I will be able to understand it.
I often feel like "the listener", the person people talk to when everyone else is busy, y'know?
The moment I start initiating conversations, though, that's when things get awkward and people are just like, "err, yeah..." or the famous "uhhh" followed by an awkward silence.
