She's tall, slim and especially she has a beautiful long black hair. She always smile thus everyone consider her a friendly person. My mom loves every members of the family with all her heart. She agreed to be a household woman instead of working out. My mother takes care of the household chorces. She wakes up earliest in the morning and goes to bed latest in the night. And during the day, she's very busy. I remember once when my mother got sick so nobody did the house work and everything went to crazy. From then, my father and I join hand to help mother whenever we have free time. She's really happy about that. When I was a kid, mom taught me to play piano at each weekend. I still remember the songs which includes many childhood's experiences. Not only taught me to play piano, she also taught me to be a better human. I love the moral stories that she told me before I fell asleep every night. We're really appreaciate mother's effort, patient and her hard work to conserve the family's happiness. My mother is an indispensable part of my life. When I grow up, I want to be a woman like her.
