Do you have any annoying co-workers? There is this one guy at my work, that will come up besides me when i'm in the middle of a phone call, or am obviously busy and have the most pointless conversations with me. Can he not see I am busy? It drives me absolutely bat shit crazy. It's not like it is just once every couple days, it's a good 3-4 times a day. I just put headphones in and just smile politely at him now, but it still drives me nuts.
