My teenage daughter's writing needs some constructive criticism that I want to give to her.
Is there anything wrong with her writings?
I feel that she writes a bad. She writes a lot of disturbing things
You should be nice and try to give guided criticism to your child. If you feel the writings are too disturbing it might help to get her therapy.
I don't want to be friends with those pushover parents who wants to be nice to their children.
That's alright, you don't have to be anyone's friend who you hardly know. You should talk to your daughter about her writings and give her the right push, because that's your job as a parent anyway.
