On this question: How to tell/ask my brother to provide his own food?
I added a Comment similar to: Do you think you're over thinking this a bit? "I'm not Mom and this isn't a restaurant, deal with it. See you at 7." Sibling relations aren't such that politeness isn't a primary concern.
It was deleted with no explanation. I'm wondering why?
If it was an Answer in Comment, I'd be happy to point that out or reword to be more commenty.
Since it's a sibling relationship, to give the best advice, it would be good to know why OP thinks politeness is so important.
