Tiny Miss Dott and her Dotty umbrella

Miss Dott takes her umbrella (in case it rains) and leaves it outside
the charity shop where she works. One of the customers, having just
bought a new shirt that he doesn't want to get wet, borrows the
umbrella (with the intention of bringing it back shortly), and leaves it
outside the music shop. A girl leaving the shop spies the umbrella
and borrows it with the promise that she'll be back in an hour, and off
she goes to the hairdressers …
And so it goes on until we have gone full circle and the umbrella
ends up back outside the charity shop by the time Miss Dott is ready
to leave for home - and discovers that it's not raining and she needn't
have brought it at all!
