Each year, we drag out boxes of worn, beloved ornaments and holiday nick knacks. After sifting through busted bulbs and broken decorations, glue in hand, we hang what’s left with loving care. Sure, there are items we don’t dare part, with no matter how garish or tacky: the “Baby’s First Christmas” bulb; googly-eyed clothespin reindeer; snowflakes fashioned with pipe cleaner by great-aunt Mildred.
