The hammer...

If anyone wants to know what it is like caring for an Alzheimer's patient?  Imagine some one hammering a nail just 2 steps behind you.  You never know when it is going to start.  It can happen while you're asleep.  Or when you are lucky enough to get a shower.  It can happen in public. You don't know.  But the one thing that you do know?  It will start.  And when it starts, it will not stop.  You cannot stop it.  You cannot control it.  It just keeps hammering.  And hammering.  Until there is nothing left but the hammer striking the nail.  Over and over.
