my boss emails me, then comes in with a printout of the email to put on my desk, and then he has to tell me "i just emailed you regarding blah blah blah, if you have any questions, let me know."
why the redundancy? why, in God's name, did you email me, if you were just going to come in and tell me about it anyways? why did you PRINT OUT an email that i can read just as easily in my inbox?
it sounds minor and petty, but when someone does this several times a day, it's enough to make you buy duct tape, trashbags, and examine the size of your trunk.
