Personal problem; having a hard time understanding where the border between player and character ends. It seems like whenever I have a character get hostile with another character in an RP, it always spills out into the OoC. I mean, I'm quite aware there should be a division between that sort of thing, but it always seems to happen with me. Do I just have bad luck, or is there more to this?

This. So much this.

I've dealt with things of that nature far too often for me to feel like its just a coincidence. To put it bluntly, I suspect that there are an unhealthy number of roleplayers who have issues separating reality from fiction. I'll drop a few examples from my personal experiences, just for the sake of showing people what I mean.

So, say that Bob and Sue are both roleplayers in a relationahip, right? Well, my character comes along and flirts with Sue's. Well, Bob decides to get aggressive for hitting on his girl.

Another example: Bill and Jerry have characters with polar opposite personalities and agendas. Naturally, their characters clash. Well, the next time Bill and Jerry talk in the OOC, Bill gives Jerry a verbal beatdown over something trivial. Well, Jerry decides to use his character to murder Bill's. Then Lily, our Gm, only punishes Bill; and ya wanna know why? Lily's character is Jerry's character's brother.

I get that some people with...less than stable minds need to express themselves and all, but this kind of thing irks me when it happens.
