These days it's an everyday occurance to have Veggies mixed with Carnivores around the table. The only problem (if that's the right word) is the extra work involved for the cook.
Over the years I've toyed with vegetarianism myself, and my youngest son, Wills, is a long term committed Veggie. When he joins us for supper I find no problem at all in preparing, and consuming, Veggie meals. I take it in my stride, and enjoy Veggie meals as much as anyone.
I remember a dinner party I held many years ago. I'd invited an eclectic mix of guests, and took particular care over the menu and it's preparation; which was 100% Veggie. At the end of the meal I asked my guests if they'd noticed anything particular about the meal, and they all instantly replied that there'd been 'no meat'. Somehow I'd thought that they wouldn't have noticed. When I then asked if they'd missed the meat, they all said 'no'.
A lot of veggies are happy to eat fish and shellfish, which makes matters easier; it's those hard-core vegans that cause the most difficulty. Everything has to be just so, and they are never afraid to ask if something contains butter, or nitrites, or non-Bio oil, etc.
When we were at college, Lady Magnon shared a house with some quite extreme Veggies. They lived entirely on steamed mixed vegetables, and unleavened wholemeal bread. OK, it might have been healthy, but a more miserable bunch of people, you'd be hard to find.
I'm very happy with Vegetarianism, but please be sensible about it. The occasional egg or fish isn't going to kill you; you may even enjoy it.
