I'm just catching up here and things got somewhat resolved after another deep dive first. I'm still trying to figure out how you can be wrong for telling a parent his child can't read, when the child can't read. Mind boggling. It's so sad to hear a teacher like yourself coming to terms with a situation by planning retirement. I know how much the kids have and do mean to you. That said, for your own sanity, I think you're making the right decision.
Enjoy your weekend camping. Hugs.
