Difficult to say...throughout my life I've been perceived as unsociable, shy, introverted, etc. because I tended to be emotionally defensive. Thus, around people I didn't know well, I acted formal and maintained a distance. With those with whom I felt comfortable, though, I'm quite gregarious...and in my twenties, I began forcing myself to reach out to other people, to BE friendly -- and I saw results. I made friends and have since then made a habit of being friendly to people. I still tend to live in my head too much and communicate myself in too formal a manner, but I'm getting better at being more casual. Also, I've been staying active and looking better since August or so, and I've been much more comfortable just being myself.
So for me, I'd say...7 or 8.
