How to feel older than dirt: ask your four-year-old grandniece, the one you call “mini-me,” to sing a Christmas song. You plan to join in heartily, assuming it will be Rudolph or Jingle Bells, but are left gobsmacked when she belts “Last Christmas, I gave you my heart, but the very next day, you threw it away.” Complete with gestures. This makes you glad that you picked this one to receive “kid charades” as one of your gifts. Remembering her look of awe last year when you spoke doll to her doll. You enjoyed your temporary unicorn status. Gone now.
