Also I've had a thought and I'm going to preface this with the understanding that I'm pretty sure I'm wrong but I can't shake it.
What if "SB" is the handler? I would hope other responsible adults in his life wouldn't let that happen - firstly, he doesn't need the responsibility, secondly, how unfair to visit and know that what you're bringing is more important. It just feels weird to me. Or maybe SBs dad has intervened for the sake of SB and school changes
