The grandfather of our story isn't like other grandparents. He wears pink trousers! And that's not all that's strange about him. People say that he's a strange old codger altogether. Some even think that he's grumpy. But as his grandson grows up, he comes to understand why Grandad does strange things, like refusing to give up his silly pink trousers. The child reader of this thought-provoking story will learn that quiet heroism can be more effective than a thousand grand gestures.
