It’s the age-old question: Do you tell your mother it was her ex-husband who picked her Christmas tree? On the one hand, she might throw it out. She might burn it, causing a fire that incinerates half the town. On the other hand, it’s delicious information. It might be fun to see her reaction … if used at just the right moment … like when she criticizes me for letting my daughter wear this or that. “Oh yeah!” I could retort. “Well, dad picked your Christmas tree. HA! Your house has ex-husband cooties.”
