*ignores the noise*
Perhaps some clarification is necessary then? Is this a simple survey of potential answers (which at this point has about reached its limit and you can likely end the thread soon) or are you in search of the best answer for your specific situation? If the latter is the case, then would you mind providing more context on the game and the players? There's a difference if you've known the guy for a while and he knows your play style, or if he's new to the group. Or if it's an entirely new group.
How well you know the person, how well you get along, how well the group gets along...determines whether you approach the guy as a personal friend, "one of the guys", an associate (perhaps a friend of a friend), or just as a GM and will focus our answers towards the ones most applicable to the actual situation.
