Let's say the Notebook. (Spoiler Alert!) The mother of the female leads character have to live with the man who she didn't fully love. Touching eh? No people in the world would want that kind of live!
Then, the Dilemma. There are situation where you don't know wether you have to tell your best friend an ugly truth. In the movie, it might be entertaining for the audience, but believe me people, you don't wanna be in that position.
From that case situation you'll find that those kind of things are more than possible to happen in one's life and it would be very hard to deal with. You also might find your life in an author's book. Anyhow, as we always knows, life is stranger than fiction, and we can do nothing but live it and let it flow.
