responsibility

"There's a responsibility we have towards animals," said his father.  "We use them.  We shut them up, keep their natural food and water away from them; that means we have to feed and water them.  Take their freedom away, rope them, harness them, that means we have to supply a different sort of safety for them.  Once I've put a rope on a horse, or taken away its ability to take care of itself, then I've got to take care of it.  Do you see that?  That noose around her neck is a danger to her, and I put it there, so I have to get it off."
