I grew up with rude people. They are very trying at times.
Honestly, they used to drive me completely insane to the point where it seems they had manifested themselves in my head because I just couldn't get it or let it go because it bugged me so much. Like JR said... Getting me riled up was a game for a lot of people because I let them screw around with me.
I don't get bothered so much now, though, it depends on the type of rudeness. If you want to be an a** about me (say, the length of my hair or how much I weight) I couldn't really give a rat's ass. I've learned to let all that slide a long time ago.
But if I see someone who's going after someone about their sexuality or how poor they are, then yeah, I still get pissed off because I think there's a point where you cross the line of being rude because you're pissed off and taking it out on someone and being just an outright a*****e.
I've had my rude moments - depending on my mood sometimes I apologize to the person (usually a stranger, unfortantely) for being a smart ass. If I'm real upset, sometimes I just don't care until it's too late. I try not too, but it happens.
The sarcasm I completely understand, too. I'm an extremely sarcastic person (in "real life" - not so much here, I find) so I try to factor that in. Sometimes it fits, sometimes it doesn't.
Anyways, I've said so much I forgot where I was going, so I'm just shutting up.
