What movie scene has stayed with you forever?

[mernuel]

I'm sure this is something that's happened to all of us, right? Who hasn't seen a scene from a movie in their life that has stayed with them forever? And this can definitely happen all the time. In my case, one that really affected me was when Forrest leaves the letter on Jenny's grave. It's so sad. By the way, Forrest Gump is an excellent movie, brilliant at times, and very, very sad at others. Which scenes from which movies have affected you the most?
