Haha, I remember still why I made that statement about mafia. There had been a bad string of games where the roles were not balanced and so the games had ended up very brutal, so I was feeling very pissy with the hosts that particular day.
Yeah I've always been a pretty terrible 'public speaker' in a way, I am often harsh and cold when making general statements without meaning to be. I do much better when I am just talking to a person one on one.
