2 weeks ago, I was walking my dog and I came across an unusual scene: A pigeon with a broken wing and its egg lying beside it. In my mind, I was thinking what had happened to the pigeon, and right after I saw the egg, it was really heart-wrenching. What I saw was life and death. A mother pigeon which sacrificed her life for a newborn egg? In this life and death scene, I feel a simple yet magnanimous spirit called love.
