I've also heard that before. A lady who's dad was a farmer told me that as she knew how the animals were treated so it was OK to eat the meat. The moral of the story is that if you treat the animals well it is still fine to eat their flesh !!I'm still not totally sure. She said she didn't want to make separate meals, but I offered to cook for myself/help out. I think it offended her a bit - she grew up on a farm, I think she thought it was an attack on her way of life. Whatever it was, she spent a week serving me meaty dishes before realising that I'd end up starving myself - at which point she begrudgingly gave in
However, I do understand what a pain it is if one has to cook separate meals. In your case you were willing to take over the task which was very fair.
