Have you ever had that moment of realisation? You're in an unfamiliar place - and this can be a city, a school, a group, whatever - and something clicks. Something to make you realise this isn't for you. It's not that you can't deal with it, it's not that you have to run away or get out as soon as possible. It's simply that this will never be "home" for you or your comfort zone.
I probably had that realisation a week ago that this town just isn't for me. I could spend some time here if I needed to. Given enough time, I could probably make a group of friends out here. But this isn't a place that's a long-term play. If I ever lived here, I'd live with one foot out the door at all times. And you're never at home when you live like that.
Know what I mean!?
