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.”
