I am an omnivore but many of my meals are vegetarian, and I prefer to eat vegetarian when I’m with vegetarian friends. Sometimes they seem to strongly want me to have meat when we eat together. I’m not sure if this is a kind of politeness, or a concern that I’ll suffer if I don’t have meat at every meal, or a desire to vicariously enjoy my eating meat. I’d be willing to accommodate the last, but I’d like to sidestep the first two. Sometimes I’ve tried to talk to them about it but it doesn’t seem to take. (Not seeking advice. It’s just…”manners” are weird and fraught sometimes.)
