First, I had no idea
so many other people like oatmeal raisin cookies! Yay!
Second, if your office-mate has not sent you the file that you need in order to work on the next stage of the project, it behooves you to go up to him and say, "I've realized we've had a communications failure. What I SHOULD have said is, 'Send me this file or I won't get another lick of work done this afternoon.'"
Of course, if one has already frittered away several hours waiting for said office-mate to send that file, this is really a lesson for *next time.* :Sigh:
