Prince of Darkness (1987)
Lisa Blount: Catherine Danforth
[Brian attempts to tell Catherine he loves her after sleeping with her]
Brian : Can I tell you something?
Catherine : Please don't.
Brian : I want to.
Catherine : Tell me next time. If there is one. Or the time after that, or... two years from now.
Brian : Who was he? The one that gave you such a high opinion of men?
Catherine : I wouldn't like it if either of us jumped to conclusions.
Brian : How do you know what I was going to say what you think I was going to say?
Catherine : Because if you don't, I don't want to know.
