The Umbrellas of Cherbourg (1964)
Mireille Perrey: Tante Élise
Guy Foucher : Why didn't you tell me?
Aunt Élise : I didn't want to say anything. I thought you knew. You didn't suspect.
Guy Foucher : Of course, over the last few months. Her letters were not the same. She didn't answer my questions. She was writing without conviction. But marrying another man! I thought she was mad at me.
Guy Foucher : What's wrong? Are you crying?
Aunt Élise : Don't be silly.
Guy Foucher : Yes, you are. Is it because you're all alone?
Aunt Élise : I'm not alone. I have my books. Madeline's coming to give me a shot. She'll keep me company.
Guy Foucher : What is it, then?
Aunt Élise : Maybe happiness makes me sad.
