After much thought, I finally decided to use this name. I have to say, this is the most suitable name I have come up with.
The old dog has a few new teeth, and life needs to go on. Unless he dies, he will always go to familiar places on time to rummage through garbage; unless his leg is broken, he will beg on the street; unless his teeth are all broken, he will give up everything and die. Die with dignity.
I don't know how I felt when I came up with this name. At that moment, I seemed to see that scene: a lame old yellow dog with bad teeth and couldn't smile. Only the eyes of the dilapidated body still had light. I looked at it and it looked at me. It's lame and I'm missing my heart. There seemed to be a thousand words in its eyes, but I could only see countless kinds of sadness. We were looking at each other, but with thousands of people passing by around us, we only saw two tired guys.
Old dogs need a dentist, and they need health in their old age, just like everyone. The old dog in everyone's heart is like a phantom representing sadness, like a story that cannot be told.
And the doctor you and I need, like an old dog's dentist, never existed.
Purpose: Life is a person's life, and who is not the first and only protagonist in his or her own life?
