You could try explaining it. I don't eat meat other than fish, but I assure whoever cooks for me (whenever someone does) that I have no problem eating everything. I get perfectly full on it, so it isn't a big deal. Most people feel bad for cooking the meat, but after I get stubborn about how its fine. They usually get interested about my weird reasons of not eating meat. I can't imagine why someone would get really hurt just because you don't eat one thing. I'm sure there will be more than a simple lamb. If there is, you might want to bring something yourself. ;P
Olympia, I can't wait to see them! I was navigating it and was all "WHAT THE HECK WHY ISN'T IT DONE YET HURRYYYYY!"
You could always go "after that easter dinner of yours, with your food smelling so awesome, I don't think I could handle not eating meat again!" Then stuff your face with meat afterwards. So many people try the veggie route, but just can't do it. So it would be believable. Just say you've been doing it for like a week. Lol.
If you want it, eat it. If you can't do it, then you could always take some home for your mom or something.
Olympia, I was just playing with you!!! I am excited, though! :P
