What if a stranger could see into your mind?
“A penny for your thoughts,” my mother used to say when I was brooding. As I got on into my teen years, she was less and less likely to get her money’s worth, and–even corrected for inflation and then some–I would probably have gotten even less out of my own kids.
But suppose parents didn’t have to offer even a penny’s worth of bribes? Suppose they could switch on some new technological marvel and know their kids’ thoughts?
