I read a news account a couple of months ago about a little boy who wandered away from the family camp site and got lost. He did stay in one place, but when he heard men shouting his name he didn't respond because his parents had taught him not to talk to strangers.

Of course, he was found and lived to tell his story. Your points 7 and 9 may conflict.
