In a similar vein, when I was two or three, my parents took my twin brother and I on our first holiday to france.
I have six siblings total, but they went just the four of us that time, though until they divorced when I was seven, we would all go on holidays to various places in Europe every year. After the divorce, my dad and twin brother and I only went to France two more times, which was kind of a bummer. We plan on doing it again at some point, but my dad was recently diagnosed with cancer. While its mild, he can't really go away as he is having constant checkups, but he's 65 this year and it might never happen.
Anyway, that first holiday, we went to the alps. Only time we ever went there. While camping on a mountain, my parents struck up a conversation with an Arab dude (apparently looked very rich).
They talked for a while. He seemed really into skiing and hiking, my mother told me one time, and was going on about how he went to different mountains in Europe every year.
After a while, super casually, out of the blue he asked to buy me. He said that they'd still have one kid, so it wouldn't be a big deal for them, and he was infertile, so couldn't have any kids of his own.
My parents politely declined, and he went on his way.
Then, three years later, while climbing Snowdon with my two sisters, twin and parents, we stopped off at a cafe fairly high in the mountains, as I recall it.
My mother, out of nowhere, got super weird and insisted we left. Last year she told me the same arab dude who had asked to buy me three years had come into the cafe, with four kids who all looked like they were actually his.
Make of that what you will.
