The week before the holidays is when a lot of people realize they’ve been running on empty. A daughter skips lunch to visit a nursing home, a son stops sleeping, and a teenage girl gets caught off guard by her first period at a drugstore or on a plane. The median age of a first period in the U.S. is 12.43, according to the American College of Obstetricians and Gynecologists, and ACOG says girls should understand that menstruation is a normal part of development. Not every girl gets that talk in time, which is when a stranger’s kindness matters most. Kindness is also a kind of self-care for the person giving it, and for adult children looking after aging parents, it can be the only kind they get this season. So today we have 12 stories that show kindness in a nursing home hallway, on a bench, at a pharmacy counter and beside a girl dealing with her first menstruation, ahead of the winter holidays.
