Recently, when I went out to work in the morning, I heard my two parrots twittering at me. This reminded me that I had two pets. When I bought them, I let them inside for a week and then I took their cage out to put it in an inconspicuous corner. Without hearing them, I quickly forgot their existence. I’m thankful to my father for helping me feed them. But their twitters told me that they’ve never forgotten me. I was so ashamed, so I began to take care of them which made them happier. Every time when I got off work they sang and danced in the cage, I knew they were welcoming me. This is my favorite moment of the day. I can forget (about) all the unhappy things in a moment. Compared to pets, as a human being, I am very selfish. I just want benefits from parents, colleagues and even children. I don't have any patience and generosity. This is the essence of human beings. Our lives are full of indifference and plagued by helplessness. We have got lost for a long time. Just like during the fight against Covid-19, some people donated as much as they could to help poor people, but other considered that this was a great opportunity to do business. From a pair of masks to the vaccines, all people just like dancers, were either dressed in wonderful gown and acted humbly or were naked. Whoever treats others with indifference, the world will pay them back in the same way.
