What an absolutely beautiful story this is - about loss, resilience, connection and growth.
Patrick doesn’t know why he collects acorns, he just knows that he feels better when he feels their hard, smooth roundness in his hand.
The fact that acorns suggest new growth, in that they are a very small nut with the potential to grow into a very large tree, is quietly central to the story.
Luckily for Patrick and this story, he lives in a town with a lot of oak trees.
