The Lost Thing
The thing is a metaphor for people who have difficulty finding the place they think they belong to. In the beginning of the film, nobody about the protagonist seemed to care about the thing , which was feeling lost.
The climax is the scene where the protagonist said maybe there aren’t many lost things around anymore or many I’ve just stopped noticing too busy doing other stuff I guess. This scene made me realize that This film is an reflection of our world.
I thought this film is also about imagination. When we were little, we use to be curious about anything but as we grow , we become less curious and stop enjoying things around us. At the end of the film, the protagonist seems to have an actual job and wears a suit. This means He ended up being like other people, no time or energy to care for other things, just living with no purpose.
