Stop in for a cup of coffee

We had to do the same thing, well, close to it to my father in law. Sometimes people in those situations start to lose focus and use want a sympathy parade, that's when you gotta smack them with reality
Yeah, they are also angry and are looking for someone or something to rage against since they feel so helpless and can't fight with the thing they are really angry at. The hard part is to not engage in the argument and smack them back hard with tough love.

My wife still struggles with that, she lets herself get drawn into the fight instead of shutting it down. She responds to the words instead of looking at the big picture and letting the words fall on deaf ears. She's getting better at it but it's still hard for her.
