Two I spoke with Glenn Plaskin, author of Katie Up and Down the Hall: The Story of How One Dog Turned Five Neighbors into a Family, about chosen families, second chances, life and death, loneliness, and adapting to change. My second guests were a couple, Piper Hoffman and Aviv Roth, who shared their decision, their feelings, and their process for reaching the conclusion to remain childfree. Their first priority is keeping their marriage strong.
