I only post exactly like how my GTA persona would, meaning. Very simple words because he's a detective, and explaining things to people using big words doesn't exactly explain much, feel?
Also since my GTA persona is a father I have to type in semi-cool slangs and all that stuff, bro.
Now if you're asking why my GTA persona is like that, it's because I almost always use a persona on the "right" side of the law but with a tendency to go above the law to serve justice. I also use fatherly personas because it's easier to do now. Plus, it's easier to get out of heated arguments since my persona would prefer a calm and collected manner.
Back then I used bad-arse, hip and cool personas which are mostly based on a mix of Lamar Davis and Trevor Philips, which back then is basically based on a little of Saint's Row and a little of how other people act in multiplayer games.
basicly back then I typed kinda like this, homes... u got a prob with that, mark? you can't even give out an argument to save your life, you dipsh*t dumbass. you cant even spell for sh*t, you moron. gtfo and dont come back until you pass 3rd grade english
^ Like that.
Now if you're asking why I even post as if it's my persona, it's because if I posted like myself I wouldn't even have an account. I'm highly introverted.
"Highly introverted." Not to correct, but you aren't "highly" introverted - you may be just introverted. I understand.
I appreciate and recognize the whole persona identity. It's really cool that you have a way to channel your voice and focus into something you feel comfortable with.
Being introverted also means being painfully self-aware. Taking your thoughts, replies, comments, etc. into a consideration "above" the level you used to, is a milestone in itself.
Glad to hear your voice on this. Cheers, man!
