This view is like a sentimental, rainy day good bye scene in the movie. However, it is not a movie, but a real life moment. The rain makes the good bye scene more sentimental. In spite of the rain, the boy is bidding good bye to someone on the train, at the window. Another boy carrying umbrella is standing at the other rail track, hunching. The emptiness of the space other than the two boys might give one a feel of loneliness.
At different stages of our lives, we do different things. As kids, some of us used to fly kites. Perhaps it is much less common for the younger generations, who live in more condensed surroundings and more used to spend time playing computer games. For those of us who had the childhood of staying in rural areas and playing outdoors, we would handmade our own kites and fly them high in the sky.
A few years after I started working, I visited Jakarta on business trip. It was late 1990.

The paperboys were very young.
