My sister is about 11 years old. She listens to everyone around her except her family. She believes that we don't care about her. Since my family was extremely busy with jobs, we did not focus on her much. I do agree that it is our fault to begin with.
However, we asked her to study maths today. She responded "no". We asked her politely and then started to use force. Regardless, her answer was "no". We have never been this violent to her. We told her she needs to get into a university. She said she doesn't care. We told her she would be a beggar. She said she is fine.
I realized we need another approach from being mean. She does not have any other hobby too. She just likes to sit at home and play laptop or read books. She cries when we ask her to go play outside. We can't make her do anything. Nothing seems to interest her except for a bit of literature. We want her to study maths during vacations so can have her foundations strong.
I am so helpless. Any ideas?
