Ok, so this question isn't to turn things into a political debate, let's avoid that, they belong in another topic. What made you into the very political person we see on here?
My dad. He was very political. Opposite of me on many views, but he showed me that you should be involved.
Hmm, I don't have a definite "saddest movie ending" in my mind, but one that comes the mind is the ending of Into The Wild.
That's a movie you need to see then. Amazing movie. Will leave you questioning your life and everything.
