Al, I can imagine you having a similar type of charisma and jocularity IRL as Chopper, but with an underlying "don't fuck with me" edge. Not saying you look like him or are a violent psychopath/ career criminal.
Okay.
In truth I am a spazz and very introverted with people I do not know. I maintain frosty, broody facade and people avoid me. If I know people and/or have been introduced, I am very friendly, easy-going and engaged (especially in topics I am interested in). I find it difficult to introduce myself or reach out to others and it is difficult for me to navigate this space.
So people who do not know me, tend not fuck with me and that is cool with me.
People I do know tend not to either, because they like me. Occasionally they do and I turn into an arsehole very quickly and probably not with much provocation. I have found that most people find the rapid change from nice, light and friendly to arsehole, disconcerting. It too is something I do not navigate well.
I do not have any issue calling out shit when I see it in real life, People being arseholes in the cinema, youths trying to cause trouble (like the little 18-20 year olds hanging around a bus stop and walking out in front of the road to make cars stop and to hassle and freak out drivers as a case in point) and the like is something I have no issue getting vocal and in faces about. But alternatively I let a lot of shit slide too because it doesn't get to me. Things that push my buttons I react to.
Most people that know of me, find me pleasant and nice IRL.
