I stole this idea from my parents, who fell in love at the age of 15 and never fell out of it. Early on, my dad got my mom a charm bracelet, and every year of their teens and early 20s, he added a new Christmas charm to it. If you’re going to do jewelry, it’s better to go for something small and meaningful than big and flashy. This idea is expandable, too: If not a bracelet, try a scrapbook or creating an ornament collection. The goal is to add to the gift every year that you’re together, ideally creating a huge memento of all your holiday seasons.
