A young couple, the wife has a highly fertile constitution, and the bedside table is always stocked with condoms.

One day, a thief came, rummaged through the drawers, but didn't find anything valuable,
and saw the box of condoms on the bedside table, casually took one—
there was only one left in the box.
Late at night, the husband came home from work, just about to make love,
and habitually reached out, but felt an empty box.
He clearly remembered there was still one.
But today, the bedside was empty for the first time.
