I have a little sister. She came into this world in January this year. Because of the epidemic (流行病), my little sister had to stay at home for the first month of her life. The job of looking after her rested on my shoulders. I brought her milk and water. I read and sang to her. I learned to change diapers (尿片) for her. It was so much fun to look after my little sister. Thanks, little sister. You made my holiday special.
