The only “rescue” I ever did was twenty years later, we were having lunch near a dock and a kid fell in. He was trashing and his parents ignored it (i.e. didn’t think anything was amiss). I simply reached down and pulled him up. It was clear that he was frightened. My friends claimed I was a hero, but I thought nothing og it -took me less time than typing this. But, it shows that it is very easy to be fooled that everything is fine.
