When my Mom was 3, in 1934, she was playing in the front yard when a man and woman pulled their car over and asked her if she wanted to come with them to “go get some candy.” Because her mother had drilled it into her that she needed to ask first, she told them she would go ask her mother and be right back. When she and my grandmother came running out a few minutes later the car was gone.
These things have been happening for a lot longer than most people realized.
