Grave of the fireflies

Oh dear, after watching this Japanese anime movie, i could not stop crying, it was so sad and the feeling can't be over soon as it reminds me of my rabbit - Robin a year ago. The story "Grave of the fireflies" is about a boy who loves his sister so much. During World War II in Japan, both of them are asked by their mother to leave the house as the enemy kept bombing the area. As the bombing stopped, the mother was bombed and died after she was injured badly and the father who is a Navy Officer died too. Therefore, left the boy and his small sister. Both of them was asked to stay in their aunty's place but the aunty took advantage on them, and they moved out of the house to live under a bridge. At last, the sister died of the lacking of nutrition in food. This is the saddest story that I've watch as the boy cremated the sister himself and he died after a few days as he was starving for food. I can't imagine if this happen to me though, I will commit suicide I guess because it is really difficult to stay on alone. During the war, who do you think is more fortunate? the alive or the dead?
