Hi!My name is Sierra.I am from Tainan,but I live in Taipei.I work as a nurse in the Emergency Room.I also study for my master's degree.In my free time,I love go to gym and do weight training.I always control calories,but ice cream is my favorit dessert. Today is the last day of Black Friday, so after work, I went to Costco and bought some things, such as fish, chicken, milk, and yogurt. What scared me was the crowd of people. It was hard to walk, and the checkout line was really long.
