Let me introduce myself ! My name is Indrianingsih and people usually call me Indri. I was born in Malang, Indonesia 16 years ago. When I was 5, I started study in Darma Wanita Kindergarten. Then at 7, I continued my study in Elementary of Mulyorejo 3. After graduating in 2008, I enrolled Junior High School 1 Malang. And Senior High School 5 Malang is the school that I’ve choosen to continued my study after graduating in 2011. Now I’m in grade X. My mother says that I’m beautiful girl. I think so. I have black and wavy hair. My hair is short like Rihanna. I always wear vail when I do my activities out of my house. My eyes is black. I have beautiful eyelash. My nose is pointed. I have full lips. My skin is brown like usual Indonesian. My body is not tall but not short too. About 7 cm shorter than Dianti, my beloved friend. In the future, I want study abroad. Maybe in Al-Ahzar University or Oxford University. After graduating, I want to be successful entrepreneur. Because, I want give a jobs for jobless. But in other side, I want to be a doctor. I want to help people to heal their disease. Wish my dreams come true, amiieen.
