You can no longer recognize my appearance, you can't hear my voice, you can't touch me, and I can't touch you. The person next to you didn't say anything, he just stood beside you quietly and looked at you. He is always praying for something, maybe he is hoping that I will come back, or maybe he is looking forward to you, hoping that you will see the mountains and plains, hoping that you will hear his voice and my words calling in your ears.
