When I have to go home during the holidays I have the dilemma of deciding whether it is worse to eat animal products or to argue with my parents. Normally I'd compromise and agree to eat small quantities of milk and eggs and only eat meat in cases where it would be wasted if I don't eat it. Now Mum often cooks too much meat and tries to persuade me that the leftovers will be wasted if I don't eat them. If I eat them, she'll keep using the same trick. If I don't, she'll say that I'm being irrational and betraying my principles against wasting food.
