If I like steak and you're a vegetarian, and I'm feeling altruistic according to normal human standards, which do I give you? Steak or vegetables?

Well, if you want to do something that I would think was nice, then you give me whichever one I'd rather receive (presumably vegetables).

But are you concerned about what I would want, or what you would?

It's time to go teach those baby-eating pebblesorters right from wrong!

(I don't have any opinions about what to do for pebblesorters. Morality is about reality.)
