>>1196874I remember this one really interesting episode of the British TV show 'New Tricks' in which this young boy has mysteriously disappeared for years and years, with not just the police officers for decades baffled but neighbors from the area feeling confused as all hell in a scared, worried way.
It turns out that the kid was literally picked up and hoisted away from the neighborhood by his biological father who'd just kind of showed up out of nowhere and then left Britain soon-ish afterwards, away from the child's other family, his classmates, his friends, and so on.
While fiction, of course, it does demonstrate the truth that sometimes people just sort of seemingly "poof", and then learning the truth is depressing at a level to where you wonder if it helps that much.
