You think you know what goes on in your town. You are sure you have everything that goes on in your house under control. You would swear you know exactly what you will find inside your closet when you come back from a vacation. Well, you have no idea.
You may find the clothes and other stuff you left behind, or you might open the closet door to discover that a new ecosystem, like these mushrooms, took over. Time to move, buddy. At least your suitcases are already packed!
