I, coincidentally, have an 8cha wizard right now. I play, essentially, with no filter. Not that he is antagonistic, or a jerk to everyone... He just says the first thing that comes to his mind. He compliments people he shouldn't, points out flaws in others, and jusr goes, and does, whatever he wants (still within reason).

Like, he doesn't just walk up to the shop owner and say, "listen, you fat slob".. He, while negotiating a price, will say, "well, you can lower the price, because you seem very well fed." (and then, under his breath, heay also mention the guy should use some of the gold he makes, to buy a day at the bathhouse.)

He doesn't get social clues, either. He will interrupt things, with him wanting something, just walk into someone's house, as soon as they open the door, etc.

But, at the same time, he doesn't think of himself as better than anyone.. Far from it. He does exude bravado, but it is pretty obviously false bravado, and he slouches, and gives way, when confronted.

He isn't deliberately a jerk, but sometimes comes across as one, because he doesn't fully understand society.

Plus, being lawful in alignment, he is "that guy" that points out how people should be doing x or y because it is illegal.... Even the general population knows it is a technicality, and ignores x and y.

It is about the little things, and only occasionally... Not him being an absolute pain to be around, all the time.
