Really? It isn't LITERAL!! (Titanic mumblings)
Okay, I just cannot take it anymore. I have got to rant about Titanic. Yes, the movie. The one with Leo-the-former-heart-throb-of-the-tween-set.

The scene. In the end. Where the redhead chick promises not to let go. We all there? Yes. Okay.

When she promises not to let go, she doesn't literally mean letting go of his hand. It's a throw back to the beginning of the movie when she was going to kill herself and he talks her back over the railing. (Remember, he promises then that he won't let go and that he'll get her safely back on the other side of the railing? No? He does. Trust me on this one). The line symbolizes (symbolizes!) that, just as she chose to live then and let Leo save her, she's choosing to live now and finds the strength to survive and then to go on and live her life the way she wanted. So when she says, "I'll never let go" and then lets go of his hand, she's promising not to kill herself and not to waste away in the life that everyone else expected of her. She's promising to live. IT HAS NOTHING TO DO WITH ACTUALLY HOLDING THE DEAD GUY'S HAND.

Honestly!
