For eight years, Riri has been an orphan. She has lived in the orphanage for six years. She has lived there because she has no relative to take care of her. Her grandparents have died. Her only relative is an uncle from her mother’s side. He is a scavenger, and his house is very small. He has five children. He has put her in the orphanage because he wants her to get better care and to go to a good school. We know that her uncle and his family love her because they have visited her. Riri is very caring. She is an active member of the charity group of the orphanage founded early last year. She has participated very actively in the group’s activities. She and the other members of the group have made and sold handicrafts. The charity group have done one thing for street children. On the orphanage’s 15th birthday, they gave each child twenty thousand rupiahs. They also have done one thing for poor families. Early this month they gave each family a gift containing sugar, cooking oil, and rice.1. How long has Riri lived with her mother?
