Have you ever lost something in your house & just never found it again?

For example I had a debit card that was sitting on the armchair and I lost it, no one had been in the house and I found it two years later in a gift bag in my room

Dropped my glasses and they broke, one of the arms of the glasses I have just never found again

Lost a window key somewhere deep in the realms of the kitchen cabinets never to be found again
