Friends should be like zero''s. When you add, they are the same. When u subtract, they are again the same but when u try to divide, they become INFINITY.
Friendship is like a string, when it breaks, it may be tied again but a knot comes there at the joint. So be careful about your friends and never try to break your friendship because it may be made again but there will be bad impression of break is left in the string of Friendship
