It's interesting how for some people, when you suggest to them that ANYTHING be changed to something different, they take as a criticism of how things are right now.
My late H and I used to have this discussion. He was not fond of change. If something-- schedule, meals, furniture arrangement-- was a certain way, then suggesting a change was the same thing as saying that the old was was bad and needed to be thrown out. If we have hamburger for dinner every Monday night and one day I want chicken, "What's the matter, you don't like hamburger any more?"
This can be generalized into: "Why don't we do/eat/go [insert suggested new thing]?"
Reply: "What's wrong with the way we do it now?"
"Nothing. It would just be nice to do something different."
"You don't like the old way any more? So I guess you've been pretending to like [old thing]? So I guess you're disappointed in me because I still like [old thing[?"
