As parents of young adult children, we reminisce about stories we read to the kids in their toddlerhood, like Santa Mouse and Jan Brett's Christmas Treasury. We still use many of the same holiday-themed cocoa mugs, and I devoutly unpack the Christmas dishes like the treasured heirlooms they are (though their value is solely sentimental). The Advent calendar I bought on clearance years ago is filled with chocolates yet again, the magnetic doors struggling to hold shut. Christmas decorations from our 20-plus years as a family are spread throughout the house, the twinkle lights ready to be strung and a space waiting for a tree.
