JEWELRIES

A couple went on holiday for three weeks. They carefully locked their house, and had a neighbor check on the place while they were gone.

When they returned, the wife was distressed to learn that, because of a power failure, she had lost all her fine jewelry.

She had hidden the jewelry in what she thought was a very safe place.

She was not robbed. Her jewelry was lost by accident.

Why?

ANSWER. THIS ONE IS TRICKY😂
