It reminds me of the movie Chinatown:
Evelyn Mulwray: She's my daughter.
[Gittes slaps Evelyn.]
Jake Gittes: I said I want the truth!
Evelyn Mulwray: She's my sister...
[slap]
Evelyn Mulwray: She's my daughter...
[slap]
Evelyn Mulwray: My sister, my daughter.
[More slaps.]
Jake Gittes: I said I want the truth!
Evelyn Mulwray: She's my sister AND my daughter!
