Dude, I don see the problem with ur way of talking, but it seems that some people in the chatroom felt that you where laughing at them, why? i dunno, a person mid is way too complicated to know.
So, if someone tells u to speak normal again, then just speak normal.
But seriously i dont see the problem, it was just an RP -.-
And to be honest that Emo RolePlaying thing pisses me off, but feh, its their Chatroom i think they have the right t RP anything they want XD and we must respect their desition.
