The Indispensable Man

My aunt used to quote this poem to us often. She was a storehouse of this kind of verse and I loved it. She is with the Lord now and I wonder if she ever knew what an impact she had on me.
I came across a blog here with a title to the effect that this personhad been gone for a week and no one had noticed. Not to be unkind to this lady, but the statement did bring my aunt's poem to mind instantly and I had forgotten it for many years.

The Indispensible Man

by Saxon White Kessinger

Sometimes when you're feeling important Sometimes when your ego's in bloom Sometimes when you think that you are The best qualified man in the room Sometimes when you think that your absence Would leave an unfillable hole Just follow these simple instructions And see how they humble your soul Take a bucket and fill it with water Put your hand in it up to your wrist Then take it back out and the hole that remains Is the measure of how you'll be missed Now you can splash as much as you want to You can stir up the water for sure Then stop and you see in a moment That the water's the same as before Now the moral to this is quite simple You must do the best that you can But you'll always be wise to remember There is no indispensible man
