Here's how an IM/email conversation just went. I'm so bad...
IM|coworker: Do you happen to know this information?
IM|Me: No, ask Dan, he would know more.
email|coworker > Dan : Dear Daniel, do you know this information?
IM|Me: BAD MOVE! You called him Daniel, now you'll never get that information. He HATES that name.
IM|coworker: QUICK! Tell me how to fix it.
IM|Me: He likes being called "Dan The Man"
email|coworker > Dan: I meant, of course, to address the previous message to "Dan The Man"
IM|coworker: How's that?
FYI Dan /HATES/ being called "Dan The Man"
LOL, this should be good.
