I loved the film so much.
In my opinion, this is all about the sadness of losing curiosity, creativity and imagination, so it is basically same with the movie "Mermaid", which we saw in class.
Every child in every place--from New York to a hamlet in China--has pure, pure mind that is not affected by anything.
But as the time passes, and as human beings get easily affected by their surroundings, most of us leave our flexible way of thinking somewhere.
"The lost thing" might be that.
I felt really emotional when I saw this movie, because I always think in that way.
Thinking how it is sad to get matured, I would stop here.
Goodnight everybody
