Don't answer the 7:30pm one, it's just pandering to her. She's well supervised, clearly not hating it else she'd want to come home, and not speaking to her parents for one night isn't going to hurt her.
Must be horrible for you to hear her so upset, but it desperately sounds like attention seeking to me.
What is wrong with you.
Best thing is he knows best and I bet you don't even have kids.
