You are gradually moving away from me, and I can't see your face clearly, only the outline is left indistinctly. There is a clear sky behind you, and a shadow behind me. Looking at your back as you turn and leave, it is blurry, like a stunt in a movie, and it dazzles my eyes. I keep watching you disappear from my eyes, waving my hand to say goodbye to you and me. You keep walking and never look back.
