Garter

Helping me sort clothes into "save" and "give away" piles, my six-year-old daughter came across a garter belt. "What's this?" she asked.
"It's a garter belt," I said. Seeing that meant nothing to her, I added, "It's for holding up stockings."
"Ah," she said, carefully placing it in the "save" pile, "we'll use it next Christmas Eve."
