Not until I experienced it did I realized that it was no easy job. I went to work when my parents were going to bed. On the morning, when my parents were going to work, I came to home to sleep.This backward schedule was very tough for me that I often felt tiring. But I am glad that I had this forgettable experience. Not only is it kind of fun to “rise and shine” along with the moon or stars, but also I learn to appreciate the hard work of those which are working while the rest of us are sleeping.【1】【2】【3】【4】【5】【6】【7】【8】【9】【10】
