My husband, Mark, and I were at my sister Lily’s wedding reception. The envelope with our $10,000 wedding gift was tucked safely in Mark’s pocket, on top of the third of the wedding expenses we’d already covered. As we found our seats, I spotted my parents. Mom was fussing with Dad’s tie, and they both looked radiant, practically glowing with a happiness I couldn’t remember them having at my own wedding five years ago.
