Childhood friends. Yes, childhood friends. The one who was always naturally by your side since you were both in diapers. A friend you could be yourself with, with nothing to be ashamed of or hide—a true lifelong companion. A presence that felt as natural as air or water.

We swapped. Our bodies. As if only our souls were switched, or perhaps only our physical forms, my soul came to dwell in your body, and yours in mine.
