Where is my Saturday?

 This weekend, I was working on my part time job. This is my first time to work whole day. I got to the office at 8:30 am and I got back home 11:00pm. I folded a lot of clothes about more than 100. It's difficult for me to make always a smile in front of customer when I get tired. But I saw my senior colleagues are always smiling, I felt that is job. Sometimes I felt it's tough, but I found the worth.
