If your spouse is working in the kitchen, it's easy to stroll in and start chatting about current events, the neighbor's barking dog, or your niece's upcoming ballet recital. But remember, your spouse has work to do. Don't keep interrupting.

Yes, one of the benefits of working from home with your spouse is that you can take those little breaks in the day with the person you loved enough to marry. But too many of these breaks can start to feel intrusive.
