its old saying that when there is a dispute or any riots are taking place or any disturbing thing happening be like culf of cow.becusae it had strong back that any body could seat on that or it has no milk that any body could drive from it .so pass by the dispute (which dosent matter's you ) like you have no ear nor eyes by this way you will be on safer side . or else some times some people blame only the person who was involved in solving the problem.
