When I was much younger, a group of us went to the jetty to fish. It was my first time. We didn't use any bait (because we, girls were squimish about worms, ee!). We didn't have to. The fishes (especially the little young ones) were gullible enough. All we needed to do was lower the fishing line with a fish hook attached. The young fishes were very inquisitive and would crowd around the hook. All we had to do was wait for one of them to open their mouth and we would jerk the hook up and very often we would hook on to their upper lip and pull this little innocent creature up. They would be jumping (in PAIN ...) and we would be jumping with JOY at our achievement!! A five-footer human, catching a 3-inch fish -- such an accomplishment!!
I tell this story in shame. My only defense is "we were young", "we were having fun", "we didn't know any better"...
