Your life is like "blocks" in which your memories are on, the feelings of solitude are filled with sadness as you pass through those blocks, because the past always seems better than future.
It is such a lovely movie, as the old man's memories were passing I felt some kind of nostalgic sad feeling, but at the same time I felt comfortable.
Kunio Kato was able to put so many feelings on this movie and pass them to you.
The music and the drawing style helps to make the animation deeply and give it a sensation of serenity.
This is the best short film I've ever seen! I definitely recomend it.
