Setting: it is in somewhere in the modern country.
Conflict: person vs. society. The boy (and the lost thing) was(were) trying to oppose the trend of the times as it passes.
Climax: the lost thing and the boy went to the place where other lost things are.
Symbol: the lost thing. When it was first found by the boy in the country, or suburb, it looked lonely, but when they got to the place at last, it regained the power, got active, and looked happy.
Irony: even though he could see the lost thing when he was young, he was getting hard to see lost things as he get older.
Theme: do not forget the feelings that we can feel during our childhoods.
I think the lost thing is the things we can use if we fix the broken parts of them.
