Every December, my family piles into our 2001 minivan (275,000 miles and counting) and heads to Buffalo to visit my mother-in-law. I call her “Grammy Yes” because whenever my kids asked Grammy a question, the answer was always, “yes.”

“Yes, you can have chocolate-covered potato chips for breakfast.”

“Yes, you can stay up as late as you want.”
