It depends. Sometimes all day via IM. Sometimes just a couple times. It's rare that I hear from him only once late in the day or not at all. I figure that's when he's super busy, or stressed out, in a bad mood and just needs space. We work together and for a while we'd also see each other several times a day. But my boss told him to stop. Good thing he has an office I can visit instead. And we have meetings we have to be in together maybe twice a week.
