Gathering together with family over Thanksgiving, shared memories came up for discussion from earlier days together in the family circle. With the darkest day of the year approaching — Winter Solstice, Dec. 21 — my sister and I talked of Christmas remembrances together and then apart as we grew, married and had our children. Some were shining and happy, some ho-hum, and some either disappointing, lonely or sad. My husband offered some of his look-backs, too. One thing stood out above all else: Christmastime is really for the children.
