Even if one human most of the time is wolf/monster to the other human we still need each other sometimes. If I remember right once or twice I choked on food. So I suppose I could have died if somebody else would not have been around to hit my back. I now read that this is quite common cause of death in america. I wonder if this means that many americans live alone and don't have anyone who could help them in such situation.
Interesting question. Or, if many Americans are greedy eaters.
