Is he really different to all the others?
I was worried about discrepancy in information too. I've not been actively lying, but I'm not above misleading if someone asks a question I don't want to tell them the answer to. Thats not materialised though.
In real life I'm less argumentative, quieter, less overtly opinionated, nicer, and I react to what people have said using my face and tone more than words which I use here (because I can't do proper faces here ). I'm mostly argumentative here because people seem to feel free to run roughshod over others online, and say stuff like 'Ok, you disagree with me.. and I'm a mod.. KICKBAN' whereas in real life.. there is no facility for that so people have to be more reasonable towards each other.
That said, I am still the same person reacting in this situation the way I would if it appeared in real life.. it's other people who are different .
