When you are at work and you send an email saying something like 'Hi XXX can you check some shit out for me' and they reply 'Yo ZKB just checked that shit out for you. Here's what you wanted to know' Do you leave it at that or do you reply again? I always send antoher email going 'Cheers XXX' but they probably wonder why I'm doing that and think I'm the kind of dick that always has to have the last word.
