I work remotely so most of my coworkers also work remotely. He lives far from me. I've worked with him for over a year. He calls me every day. For the 8 hour work shifts we work, we average about 2 hours of talk time a day. When he's not calling he's IM'ing me. It's mostly him talking about general personal stuff. He has a GF. (he rarely brings her up) They have a long distance relationship. He goes and stays with her for a month here and there and he still calls when he's with her but not as friendly as his calls when he's not with her. If he has a GF, why does he call me so much. I know for a fact he doesn't call any of his other coworkers this much or talk to them as long. I also notice a complete difference in his tone when his GF is around him when he's talking to me than when she is not. Why does he do this?
