I , like earmes say yes M'am and Sir alot. As southerners I guess we are just raised with that kind of curtiousy.
Other than that I act and speak here as I would if you were in my home. (Which is sometimes obvious in my spelling)
Unless someone is being a fool or really gets me going I don't do the whole "tough guy" thing. And that is only here, in the midst of friends. Just like in life I have no enemies and have no desire to make any.
Pretty much the same, except for a few things. Around strangers I'm usually quiet and mature, but around my friends I'm louder. Most people who know me think I'm really funny. I get along with people really easily in real life, and I have a few enemies here and there, but not too many, and none of my enemies are even worth any effort.
So yeah, around here I'm not too loud, I don't joke around a lot. I usually don't involve myself in arguments here...
