The year our oldest son was born, my parents gave my husband a ski helmet for Christmas. As he opened it, my mom told him “You have a child now. You have to take care of yourself” (subtext: we’ve seen you ski the trees and it is better for everyone that you wear a helmet). Figuring that what is good for the Christmas gander is good for the New Year’s goose, I went out and bought myself a helmet in the post-Christmas sales.
