I have 3 cousins, raised in the same home.
1 is vegan, 1 is vegetarian, and 1 is a meat lover.
Their parents have 3 holidays. EG; 1 Thanksgiving dinner with each.
I'd say "to hell with that" ... they want to eat something different from what I'm serving, they can cook and bring their own dish. LOL
Then I have to laugh at "vegetarians" who won't eat meat ... unless it's fish. I think they actually have an official name for that, now.
But to say "I don't eat meat, because I don't want animals to suffer", then eat fish ... I guess they don't think fish suffer. :rolleyes:
