Now, the window is clean. You look out the window. It is square and empty. Light wriggles into it from end to end, filling every empty, bright nook.
You aren't ready to see what's beyond the window yet. But you made it clean. You made it a window again, rather than a wall, rather than a gray box that closed you in on every side. You made it a portal. Anything may lay beyond. You are not afraid.
