I have deliberately kept my daughter and her best friend from being in the same class at school
Why did you stop your daughter from being in the same class as her best friend?
I want her to be able to focus on her schooling and not be distracted.
You should sit down and talk to your daughter, since communication is the key to a solid relationship. If she finds out you've been interfering with her and her best friend, she may resent you for it later on.
Don't even. I don't give a fuck what consequences this could bring.
I understand why you would want to do this for her. I was just trying to say she could be really hurt if she finds out. You should do what you think is best for your child.
