Were there no cameras to record who took the bag?
I might look silly patting myself down
(One happening was actually in Australia - someone had taken my luggage from the pickup spot at the airport. It had a fair bit of value in it. Later that evening it was returned to my hotel by a taxi with everything still there).
but as my therapist has said, "you did something idiotic, but you are not an idiot." Yeah, it's semantics, but it makes a difference in how you see yourself.
I have misplaced many, one I dropped in the ceiling while doing some wiring.
For those wondering, this happened because here everything is upside-down, so the ceiling is down and the floor is up. So Valkie dropped it down, towards the ceiling.
I do this too.
