what will you do when you .........

In my culture, it is a taboo for a child to tell the mother not to interfere if she does bad to others. We find it shocking to hear children command or overpower their parents telling them they know what is best for them. If I have a child like what you described, I'd give her/him an ultimatum to leave her bestfriends as they are not considered as friends no matter how painful it is. I'll tell her she needs to sacrifice leaving them if she wants to be successful in life. Better yet, as a parent I have to strengthen the family ties, spend more quality time with them and be their bestfriend at the same time.

In these days, children are hard to control. They do not respect their parents, and some will 'climb over the head' of their parents. They do not take advice of parents. Especially when they get into school, they will influence each other. Hence, what kind of companian they get along with is very important. And now, your daughter is mixing with this bad influence friend who may make things worse. She may have learned nasty stuffs from this friend of hers, like asking you not to interfere which could be taught by her this so called friend, if your daughter had never talked to you in this way before, who knows. Spend some time with her, let her feel that she should listen more to you and not her friend.

It sounds a bad thing.If I come such a thing,I will be mad.I think I will talk to her and I will ask her teacher to help me.I must be strong enough to let her leave her bad friends.
