Disregard what I said before. I cried once, after seeing a really sad part of some movie I watched as a kid.
It was about three animals, two dogs and one cat, and they can talk to each other?
I forget the name, but I got really upset when the little cat fell off the top of the waterfall. :'[
Since I watched it at a daycare, I waited until my mom put me back into the car, and then I bawled my eyes out. The cat was saved by some farmer at the bank, but seeing the little feline all helpless and falling, wet, alone, and scared... it really shook me, since I love cats. God, I still get sad over that and I'm 16.
Besides that, I've never cried or come close to crying while watching a movie.
