Yes, and most often it was my own rules that I'd bend. When the kids were little I had a rule that there was no eating in the living room. They could eat at the table, or even walk around with food or drinks somewhere else - but no living room eating for them (or anyone else, like their father or me). I might break the rule for an occasional guest, but most of the time I didn't want food in the living.
However, when their father would go on an overnight trip somewhere, I'd rent a movie; put out a blanket, get something like Chinese food, and the four of us would have a "picnic" in the living room while we watched the movie. Since my husband resented the no-food-in-the-living-room rule, it had nothing to do with his going somewhere. It was just our way to "be wild" and have some fun as "just the four of us". (It did backfire once when I made the mistake of renting "Land Before Time" and all three kids ended up in major tears when Little Foot was separated from his mother; but that's an "answer" for another question and day.)
