From a conversation between me and mum today:-
But why is it OK to eat fish if it's not OK to eat beef or pork or other meat? Isn't fish really just another type of meat? Is it because they're in the water? What if cows could swim? Would it be OK to eat cows then? Would it? You know, this “no meat on Good Friday” rule looks like some silly arbitrary restriction made up for no reason, and I'm sure Christianity doesn’t want any of those.
I’m not the easiest of people to live with.
