"On Monday morning, William went with Mum to play school for the first time." But when he gets there, William doesn't feel like joining in with the painting or the games so Mum stays with him.

Then on Tuesday, Mum and William notice another little boy who also needs a bit of encouragement.

Gradually, as William and David's friendship develops, their confidence does too and on Friday when the sun comes out, both boys are able to say good bye to their mums and go out to play.
