Me and this guy have been having ups and downs, don't see much of each other cos busy on different shifts. Yesterday as his car pulled into the parking lot, I was standing there and as he was parking he waved to me... Then when he got out we had a brief conversation which didn't last long cos some other worker was walking towards us. We have been having a secret relationship on and off at work so he tends to act really aloof which is causing tension for me. But him waving just cheered me up... does it mean he still likes me? If you guys didn't care about a person would you still wave as an expression of greeting? Or was he genuinely happy to see me standing there you think? We kinda hookup now and then if our shifts are the same.
