Tell me a joke. I want to miss someone. I want to say it in a joke.

1. I was still waiting for you, but you forgot that you had been here. I'm lovelorn. How could you lose me? 3. Let you be crazy without me, and let me be strong in the world without you. 4. If you smile once, I can be happy for several days; But seeing you cry once will make me sad for years. If you walk with your hands closed, you won't get lost. You will never see me when I am loneliest, because I am loneliest only when you are not by my side. 7. I am nostalgic because I can't see you and the future.
