Feed a wolf, gain a friend.
Feed a wolf a friend, lose that friend, but also gain a wolf-friend.
Break even on friends.
BUT…
Feed a wolf the wolf that you fed your friend to, lose that wolf-friend (and the friend inside the first wolf), but gain a friend in the form of the second wolf.
Net friend gain: -1
BUT…
Eat that second wolf, gain a friend (second wolf), a friend within a friend (first wolf-friend), and a friend within a friend within a friend.
Net friends: 3
THEREFORE…
Eat a wolf, make some friends.
