My husband and I own a construction business and so we work together daily. One day, I realized we needed to set some boundaries.  I was in the kitchen, getting dinner ready, with my hand literally inside a turkey. My husband walked in, unrolled a house plan, laid it across the turkey and said; "Can you take a look at the electrical here?" What!?! We had a talk and set some ground rules.  It's been 15 years and it has worked out great.
