I Just Barely Care About People

Philosophy student #1, about biomedical ethics: Yeah, we just don't know enough yet to go around screwing with genetic manipulation. Like, cloning people. That creeps me out.
Philosophy student #2: That sheep they cloned, Dolly. She died recently, didn't she? She was like five or six years old.
Philosophy student #1: Yeah. I don't think she lived very long.
Philosophy student #2: What's an average sheep lifespan?
Philosophy student #1, in defensive tone of voice: I don't know! I don't care about sheep!
