You and your friend exchange glances, and you head down the hidden path. The path goes deeper and deeper into a forest. While the trees block out the sun, you can feel that it's getting late as the light begins to fade.
Right when you are about to nervously head back, you find the most intricate and amazing tree house you have ever seen. You see a note on the tree, and you cautiously walk up to read it. It says: "To whoever finds this haven, may it provide you with a place to revel in the beauty of nature."
You and your friend smile. You head home and promise to come back the next day.
