You’re never too old to learn about cultural diversity. I realized this over the weekend, on the eve of Hanukkah. My mom, a fourth grade teacher, told me about an incident she’d just experienced at a local party-supply store. She was shopping for her annual Hanukkah lesson, in which she briefly teaches her students the meaning of the holiday, demonstrates how she lights our family menorah, and leads them in a spirited game of dreidel. Everyone goes home with a little bag of chocolate gelt, a dreidel and maybe a Hanukkah-themed pencil.
