I keep watching the scene in Eternal Sunshine of the Spotless Mind (starting at about 1:16 in) where Mary and Howard are left alone to work on erasing Joel’s memories, and Mary speaks the following quote (from which the movie gets its title):

How happy is the blameless Vestal’s lot! The world forgetting, by the world forgot. Eternal sunshine of the spotless mind! Each pray’r accepted, and each wish resign’d. - Alexander Pope
