Your brother in law who is over 600 pounds would not be welcome anywhere around me unless he was talking to me about turning around his health problem.
I can get snippy that way.
My loving life includes a lot of tough love too and if it at least helps ME and doesn't hurt THEM I can do it.
There are telephones too.
I have no family so I can't judge. But I can get a good birds-eye view of family problems too...❤️
