To me another good scene is in Forest Gump at the end when Forest is standing in front of Jenny's name. Every time I see that part of the film, I think to myself, "Now, he doesn't have to wonder where she is anymore." considering the fact that she was always leaving him.
1.) She left him after he saved her from the guys at the strip club.
2.) She left him in Washington D.C. to go back to Berkley, CA I think it was.
3.) She left him after the night that they conceived Forest Jr.
