Floppin'

So, tonight my son was being awful quiet in his room. I asked (from the living room) what he was doing, and he said he was feeding his fish - which was what he was supposed to be doing. When I went to tuck him in, I noticed the lid to the fish tank was on a little crooked, recalling that it was like that last night too and I had fixed it then. When I asked him about this, my dear son said, "I wanted to see if they really flopped around on the floor"! I could not believe this! I was so appalled and he was obviously upset either by my reaction or by whatever it was that he "discovered" during his experiment. The fish seems fine. He's missing part of his tail. Poor guy. Words fail me....
