In order to get enough attention from their parents, children will do whatever pleases their parents. She must have wanted attention. She had probably been trained to stay in the nest as if she were under her fathers spell. If this influence had come after she had developed her own personality, things might have been different. Since she never did anything wrong in school, teachers couldn't notice it.
Children learn from mistakes.
It is essential to make some trouble when they are little. In order to let them do so, parents and teachers sometimes should create an environment that children can feel free to do or say anything they want. When they're ready to leave, they will fly from their nest with their own wings to make their own nest. Perhaps because of this memory, I began to focus on quiet or well-behaved children if they seem hiding their 'needs' inside. I've felt guilty since that time because even though I had noticed my friends' breaking wings, I couldn't help her at all.
