I've suddenly remember the first time I've cried watching a movie.
and it was
Grave of the Fireflies, japanese animation.
I'll never forget how I felt when I watched this film. I was about 8 at most, my parents rented it, thinking it would just be another Japanese animation about families or whatever, because the chinese title literally just meant 'Goodbye Fireflies'
And there I was, watching it on my own, and as my parents recalled, they suddenly heard me crying
I guess one of the reason is that the family members in the movie is the exact copy or mine - mum and dad, with me as a big brother who loves his sister to bits. The only difference is that in the movie, they all die
I hated that movie, and I still hate it after all these years, I'll never watch it again.
Everytime it's shown on tv, i'll just switch the channel right away
