I do hope both your head and your tail aren't hurting too much today.
Please do get that floor repaired. We are getting too old for that kind of "trip"!
I lost my paring knife the summer before last. It disappeared completely between the kitchen table where I had been using it and the sink. I could not find it when I went to wash up.
To cut a long story short - I searched the entire kitchen twice and the bins three times, then conscripted DH to help search.
No joy.
A year later to the day - it turned up on the middle of the table where I had been using it the day it disappeared. It had definitely not spend an entire year there, as the kitchen had been completely cleaned more than once in that time.
DH swears he too has no idea either where it went, where it was for a year, or how it got back!
