This is a difficult question to answer.
After working for a day, I went home and sat on the sofa with a bottle of beer in my hand. I enjoyed it at this moment. Can you imagine? It's just a sofa and a beer. I also encountered some problems that bothered me and saddened. For example, the mortgage has to be repaid, and the cat I raised is lost. Probably this is life. I am not absolutely happy or sad.
