he's a pretty nice guy irl.
some people might say he's kinda distant when you talk to him or cool, but keep in mind he's meeting you- a stranger- for the first time and only for a few minutes, and probably had already met several strangers that day before you.
i found him to be very nice when i met him and we talked for a while, with him generating some of the conversation. i think he was a little more open with me due to the fact we were introduced by a mutual friend.
