The way Home (2002 – Korean)

An unemployed mother leaves her kid in her mother’s house in an underdeveloped village. The plot of the movie fully revolves around the grandmother and the boy. The boy who gets annoyed by his grandma begins to realize how much she loves him and much more in his short stay at her place. At some point of time the kid says “if you are sick send me a blank mail, Ill understand”. And I should say a very selective casting makes this movie a biggie. The movie ends with the note “dedication to all grandmothers”. Indian Remake of this possible??
