Talk with Dad about Anissa

I called to talk to him about Luke spending the weekend with them but then the conversation turned into him venting about Anissa. I had no idea she was not working nor going to school.....well, when Dad asks her how many credits does she still have until she grads- she says she has no idea.....exactly, how is that possible. So, now when she stays with them, she stays in her room bc she is afraid of dad, but I explained she is afraid of the truth, not him. He does not know how to get through her that she has the best opportunity to just go to school- there will be plenty of time to work. So, all she does is hang out with her friends when they get off work (around midnight), talking on the phone then sleeping until the afternoon. I may have to step in because when asked what Rachel thinks, he says I think she knows and doubts she cares. Well....someone has to care, even though it may not be my lane but I love her and need her to get back on the right track. I may have to reach out to Bill and Julissa to see if they have any ideas on how to address it without arguments from her or Rachel.
