I was reminiscing, and thought of this thread. For at least 20 years, my Anglican grandmother used to serve fish
every single time we visited, despite it not being what they usually ate. It was too awkward to ever bring up, but she was presumably trying to be understanding, because (after all) what else do Catholics eat?
We were not overly fond of fish, as children. Particularly as, trying to add variety, she’d serve things like squid rings. I’m not sure we ever said anything to encourage this surfeit of fish, but she meant well (I hope).
Also, in a discussion about the role of faith in Girlguiding, a well-meaning devout-but-vague Protestant was explaining that all sorts of faiths are welcome in Girlguiding, and the Promise can be altered slightly to accommodate this. I agreed, with the example often given that a girl can promise to do her best to love “Allah” or another word or phrase as appropriate, as all that is required is that a girl try her best to develop her own faith and understanding of her religious tradition. The Protestant well-meaningly added that people worship all kinds of different things, such as Krishna, or (nods at me) some people worship Mary…
“Catholics don’t worship Mary.”
amused expression
“Well, maybe some people…”
“Nobody worships Mary.”
“…I’ll stop digging, shall I?”
I do love her

All the girls there knew I’d been to Mass that morning, as I’d had to arrange it beforehand so that we had enough adults around.
That evening, a different well-meaning Protestant (who was
borrowing my “New Catholic Bible” because her own Bible was too hard to understand) attempted a very strange discussion of the Assumption, in which she seemed to be responding to an imaginary conversation involving things I had not said.
“So if the Pope says it’s true, it doesn’t bother you that it isn’t in the Bible?” is not a valid response to a brief explanation of the origin of the Assumption in early Christian writing, and the different traditions in the Eastern and Western Churches. I had not mentioned the Pope.
