You can interpret this picture in many ways:
The spiritual person, “Find your source and grow deep.”
The individualist, “Be yourself. Even if you’re all wet.”
The pessimist, “That tree is gonna drown.”
The visionary, “Ferries. I see ferries!”
The photographer, “Too much water.”
Calvin says, “What water? I smell rabbits in those hills.” 
Tired of the forest, Martha the tree forges ahead, looking for a better place to put down her roots. This is what you get for reading about Ents in Tolkein’s Return of the King–you might believe that “all things are possible” and choose to “go for it!”
