I'm exceptionally friendly and polite; the kind of guy who wouldn't dare complain about a meal even if I found a severed toe in my soup because I wouldn't want to insult anyone.... hyperbole aside, I definitely see myself as a very friendly individual. I'm not one to delve into conversations with strangers when waiting for the bus ect., but should something like that crop up, or I'm meeting someone new, I'm always one my best behaviour. It's only when I'm more comfortable around the person to better learn their limits for when i start being a bit more of a twat. All in the fun of banter even still...
Overall I'm pretty friendly, although I'm not excessively giddy, nor do I enthusiastically engage in conversation with strangers that often. However, I have only ever been in one fight, and have avoided conflict throughout most of my life by being on good terms with most people I come into contact with.
I'm like a 10. I'm way too nice in person. Although I will admit that Larry David is my hero. I just don't have the heart to call people out on their bullshit in real life.*wakes up to little girl singing horridly*
"shut up..what the fuck...shut the fuck up SHUT THE FUCK UP"
Unless they manage to push all my particular buttons, I find it easy to be generally friendly, even to those that might come off as a bit rude. Hell, even if they do irritate me, it's actually not that hard to keep civil. Working at an independent post office, I see a lot of people; I don't know them, their habits, how their days might've been prior to them walking in, so I choose to give pretty much everyone the benefit of the doubt.
I used to be somewhere around 4.5, which I now consider to be a little too nice. I would say 3-4 currently (I voted for 4). I'm still super polite to every reasonable person, but I am quicker to call someone on their douchebaggery nowadays.
I will say that for whatever I reason, I tend to be a little less nice on message boards than I am in real life. Maybe the anonymity makes me more honest? I'm not sure.
