Akari Shinohara: Hey... They say it's five centimeters per second.
Takaki Toono: What do you mean?
Akari Shinohara: The speed at which the sakura blossom petals fall... Five centimeters per second.
Those are the first lines of the amazing animated film "Five Centimeters per Second" directed by Makoto Shinkai. It's a heart warming story with incredible animation and beautiful music, too!
I strongly suggest that you watch the film.
