In his parenting memoir Home Game, Michael Lewis shrewdly notes that all it takes for a couple to start fighting, really, is for them to go out to dinner with another couple whose domestic division of labor is slightly different from their own. “In these putatively private matters, people constantly reference public standards,” he writes. “They don’t care if they’re getting a raw deal so long as everyone is getting the same deal.”
Not universally true. Many couples more mature than this, but can be source of some pointed humor and elbow-jabbing. Maybe that can lead to small changes too?
