What is the meaning of [A good tale is none the worse for being told twice]

Children, in particular, love to hear a story again, however many times they
heard it before.

> ‘Mummy, please tell me the story of the girl who had two wicked sisters, who
went out and left her to do all the housework, and one day a fairy turns a
pumpkin into a beautiful coach and she goes to the ball in it, and the prince
falls in love with her and they get married. Do tell me that one, Mummy.’
