So my family just moved, and we have these very friendly neighbors. My parents talk to them all the time, and even my dog is friends with their dogs. They love to fish(they said they caught like 50 blue gills in the past few months) and they invited us and lots of other people to a fish fry. Luckily , for this one I'll be gone at a summer camp, but I'm certain they'll invite us to lots more. I told them I'm a vegetarian, and they were like "Why? You can't miss out on this! It's so good!" and then "Don't worry, we wont tell anyone if you eat fish." I just laughed at that, although I was actually horrified. I certainly won't eat it, but I don't want to refuse their next invitation rudely, and I can't really use the meat industry as the reason I wont eat their fish, since they caught them themselves. And they will probably just stare at me if I tell them I also am vegetarian for environmental reasons,health, and because I think eating another animal is just disgusting. Any suggestions for what I should do?
