My Grandson Asked The 1 Question I Was Totally Unprepared To Answer. The author's 'married' granddaughter taking the new Mr. and Mrs. for a drive. The marriage of Barbie and Barbie or Ken and Ken hasn’t yet crossed her mind, and, honestly, I feel that it’s her parents’ place, not mine, to have that conversation. Engaging with Barbie and Ken is one of the favorite activities of the author's youngest granddaughter. Recently, my youngest grandson asked me why “Grampa” and I are no longer married.
