ONE ONE HAND I think you should tell your circle of friends to shove it! Playing with characters who DON'T have perfect personalities, NAY, MAY EVEN BE INCREDIBLY ANNOYING is awesome. =\ The whole idea of RP is to see characters interact, it's dumb to say WE WON'T INTERACT WITH ANNOYING PERSONALITIES.

But. since sometimes one should not tell one's friends to shove it. Why? There are a horde of RPs out there and the majority of them have fairly easy acceptance.
