A sad word?

We all came to this world alone, and we all left this world alone, so don't be afraid, don't worry, don't struggle, don't give up, don't miss it, and don't look back. Our life is like a trip. Everyone is on the road, and everyone is walking on. Some people walk in front of you and some people walk behind you. Some people stop after a while, others keep walking and never stop. In life, there is always unexpected warmth and endless hope. Say a short sentence sadly? 1, you are mine, and no one can take it away. I won't take it if it's not mine. 2. My heart is a city, and there is always someone I can't reach. Throughout my life, I was lucky, but I was not killed. We all came to this world alone, and we all left this world alone, so don't be afraid, don't worry, don't struggle, don't give up, don't miss it, and don't look back. Sometimes, you choose to keep your distance from someone, not because you don't care, but because you know clearly that he doesn't belong to you. 5, you are mine, no one can take it away, not mine, I won't take it.
