It does look a bit like a window. The shape is square and one would step from darkness into light but it’s not really a passage into another world, just a section of the road shrouded in darkness.Kind of like life sometimes, just dark and sad and we wonder how we are going to force ourselves to take one more step , then we see light ahead. Light attracts most people, we are drawn to it ,we relish the illumination and for most we need what is present in the light to live and be happy. Someone in my life is going through a horrible darkness right now and all I can truly offer besides my love is the hope of light. Just hang on , the sun will come back.
