There is an old German fable about porcupines who need to huddle together for warmth but are in danger of hurting each other with their spines. When they find the optimum distance to share each others warmth without putting each others eyes out their state of contrived cooperation is called good manners. Well, those old German fabulists certainly knew a thing or two. When you acknowledge other people politely, the signal goes out Im here. Youre there. Im staying here. Youre staying there. Arent we both glad we sorted that out When people dont acknowledge each other politely, the lesson from the porcupine fable is unmistakeable. Freeze or get stabbed, mate. Its your choice.
