I remember when a couple friends of mine mentioned they didn’t eat meat. I had made a suggestion for a dish to try as we checked out the menu, and they simply responded with their dietary choices. That was the entirety of that particular exchange. After all, what do I care what they eat as long as it’s not people?
However, it seems my friends are unusual in that regard. I keep hearing of vegans and vegetarians who simply can’t handle the idea that someone else makes different choices.
