FOR THE LAST FIVE YEARS OF THEIR MARRIAGE, MY PARENTS DID NOT speak to each other. Not to say “Excuse me” in the kitchen during the morning rush, or even a reflexive “Bless you” after a sneeze. This was during my senior year of high school and into my college years. My mother slept on the couch in the living room, like a boarder. My sisters and I all led separate lives.
