Emma Greenway Horton: I know you like me. I know it. For the last year or two, you've been pretending like you hate me. I love you very much. I love you as much as I love anybody, as much as I love myself. And in a few years when I haven't been around to be on your tail about something or irritating you, you could... remember that time that I bought you the baseball glove when you thought we were too broke. You know? Or when I read you those stories? Or when I let you goof off instead of mowing the lawn? Lots of things like that. And you're gonna realize that you love me. And maybe you're gonna feel badly, because you never told me. But don't - I know that you love me. So don't ever do that to yourself, all right?

--In the movie Terms of Endearment (1983), which was written by James Brooks based on a novel by Larry McMurtry. 

Emma is dying, and hasn't been getting along with her older son, a resentful teenager. She tells him not to feel guilty later for how he is behaving now. She knows he loves her anyway.
