I'm trying to think of the name of a 1960's British drama about an old woman (a widow) who lives alone and is apparently suffering from the beginning stages of senility. Every time she enters her empty apartment, she asks "Are you here?" or "Are you there?" or something to that effect. At one point she is befriended by a couple who gets her drunk on cordials until she passes out, then steals from her. Her son is a mooch who comes by only when he needs something. This movie was available on Netflix but I can't seem to find it now. Thanks in advance for your help!
