If you stay at home and your partner WAH, how do you interact and/or share the space?

I'm home on maternity leave with LO2. DH WAH one or two days a week. I try to treat it like he isn't here except he has a lot of conference calls so I try to keep the baby quiet.

This afternoon I made lunch and we ate separately. After he ate he played video games for the rest of his lunch hour. LO was napping so I was cleaning. I was a little irked he was playing video games. But if he was at the office he would theoretically do whatever during lunch. Just wondering how other couples handle the shared space.
