Ma-in-law's doorbell stopped working. There was some fault in the very old wiring hiddem in the wall somewhere. It wasn't worth fixing so we got a wireless one. The most central place to put the unit was on top of a kitchen cabinet.

One day Mama complained that it had stopped working, so Tree went to get the unit to check if the battery was dead. It wasn't there, so she asked Mama, "where is that white box that was on top of the kitchen cabinet?" Mama said "It's in the garage, I tidied it away". So Tree sent her to fetch it.

"Hold it" she said and went to the front door and rang the bell. Mama nearly dropped the unit. It was working fine.
