A story for this, lets say Oliver is walking out of his store at the end of the day and he gets jumped by some crazy pegasus (Awsten) with a knife and dragged into a nearby back alley where he gets his forelegs tied back and stabbed in the torso so Awsten can play with his guts. He's a zombie so he'll be fine, it's just quite rude to do that to somepony you never met without asking first.
