So my company has called back some people they let go a while ago to do some temporary work, as we have some major projects coming due. Some of these guys I haven't seen in a year or two or three. First guy - says hello and holds up his fist in what I assume to be a knuckle to knuckle bump. I go for the bump, but he goes for the over-under fist bump. Second guy, has his hand open, held up for what I assume to be a high-five-to-hand-shake combo. He just goes for the high five. Third guy, same as first, except he ends up going for the knuckle to knuckle, and I go for the over-under. For crap's sake, CAN'T WE ALL DECIDE ON ONE BLOODY HANDSHAKE??
