Quote context

[...]

- All right. All right, Fiver. It's getting dark. I think we should get back to the burrow.

- Back to the burrow? It'll come there. Don't think it won't. It's all around us.

- Now stop it, Fiver.

- We've got to go away from here.

- When the other rabbits hear of Fiver's vision, do they believe him?

- Why should we care?

- Because the rabbits are us, Donnie.

- Why should I mourn for a rabbit like it was human?

- Are you saying the death of one species is less tragic than another?

- Of course.

- The rabbit's not like us. It has no history books, no photographs no knowledge of sorrow or regret.

- I mean, I'm sorry. Don't get me wrong. I like rabbits and all. They're cute and they're horny.
