Every now and then a family member just walks out the door and disappears. Some of the more famous cases are Edgar Allan Poe and Agatha Christie. I quoted Poe’s story below. Christie disappeared for 11 days and assumed a new name and personality. Had she not been recognized who knows how long she might have been lost.
Nick Simmons story is a classic case. He just disappears and ends up on the streets a week later. Something snapped in his mind. He could have been lost for years if he hadn’t been recognized from this random photo.
This is different from a person that deliberately leaves. Like a dad that abandons his family. That is planned and there is a specific new life he wants to create. People who leave on purpose usually don’t end up on the street.
