The only time someone else packed my case was about twenty years ago.
I was required, at very short notice, to go away to the middle of nowhere, wearing a flying suit in transit. My wife had thoughtfully packed my case by the time I arrived home to do it myself.
When I unpacked that night there were no trousers!
Spent five uncomfortable nights wearing someone else's trews that were about three sizes too big, with huge turn-ups so I could walk.
Never did that again.
