Opening a Window on a Train

It was soon after I came back to Japan from the United States. I was 

on the train, and the interior was hot and muggy in the summer heat. I stood up and opened the window above me to let fresh air flow into 

the interior. I wondered why nobody else would do the same. They 

looked like they were enduring the summer heat.

A few weeks passed, and the train interior was still hot. I wanted to 

stand up and open a window. Then an idea hit me: if I stood up, 

extended my arms, touched a window, and opened it, my act would 

attract the attention of the passengers. I would be embarrassed." I 

kept sitting on the bench. Funny that I was a Japanese man again in a short period.
