you can't describe him as your father,
just because he advices you when you are in need of it...
you can't describe her as your mother,
just because she can understand everything just by seeing your face..
you can't describe him as your brother just because he protects you and warns your spouse at your wedding..
you can't classify them under any category of relationships because they are friends..
they don't expect anything from you except your love ...
they mock at you ,knock at you ,laugh at you but never leaves you alone at any situation...
friendship is really a different relationship that god had ever created in this world..
enjoy it and thank him if he blessed you with this amazing gift....
