사랑방 손님과 어머니(1961) / Mother and a Guest ( Sarangbang Sonnimgwa Eomeoni )

A six-year-old carries messages, and boiled eggs, between her widowed mother and the quiet boarder in the guest room, neither of whom will say anything out loud. Shin Sang-ok keeps the whole restrained business at the child's height, so the parting at the end is something she watches without quite understanding.
