Why does tearing some objects put my teeth on edge? I can't stand the feeling of tearing cotton wool apart. Yet, none of my friends have a problem. In the same way, many of my friends can't stand polystyrene being scratched. Nor can they stand two knives scraping past eachother. What is the cause for this strange effect?
