Today there was more banging and loud noises in that little room again.  I guess there is nothing I can do about it, so I decided to sleep on the big bed and sometimes watch to make sure everything is done right.  Whatever it is that is being done.  The hole in the floor made a funny noise and I put my head down in there to see what was going on.  Daddy told me that I might not want to do that.  Said something about ending up in a septic tank.  What’s a septic tank?
