Oh dear!
I'd this situation as a young adult.
I was to travel to a large township in PNG.
My Mother made me promise NOT to fly in a plane with only one engine!
She had a nasty experience on my previous trip there, with an plane crashing, which she thought I was on, when I actually was having breakfast at the Papua Hotel, in Port Moresby!
I was asked by a pilot to fly with him to another township, which I would've loved to do, as I fly as often as possible, because I just love flying.
You guessed it. Small plane only had one engine!
So I gracefully declined, citing my reason why, & he said 'if that's what you've promised your Mother, you must do as she's asked'.
It was an experience I have regretted not taking, & that was many decades' ago.
Of course, that opportunity never arose again, & won't.
But knowing my luck, IF I'd disobeyed my Mother, something would've happened!
