Franz Kafka - "The Trees"

This is a very short story in which Kafka compares trees to humans. I have found it hard to work out the meaning behined this story. It is confusing what he means but I think it means that we might seem fragile and can be moved easily, but really we are hard and resilient.

Quote from the text above and sketch I drew just to start getting ideas.

But to help some more I went down to the woods and took photos of the trees , shapes and  textures. The trees textures helped me the with the sketch above.
