I think there's come a time to all of us when we say "D*** it all! I'm going to empty this pool and shut it down! No more!" Sometimes more than once......

It reminds me of the cynical quip: "A boat is a hole in the water, surrounded by wood or fiberglass, into which you throw money!" With the follow-up being "The two happiest days in a boatowner's life is the day he buys the boat...and the day he sells it!"
