The Train Lady

The first train would not reach my destination, so I detrained in Yotsuya for fresh air where the subway makes a rare stop above ground. Waiting in the mild humid morning for more metro cars, I reached for my Japanese Grammar book, though the next train, on time, rolled up before I could start studying, so I retrained and took a seat.
I opened my book in the middle, searching aimless, and yelps!, squeels!, a soprano in fluttering falsetto, chirped standing by the door to my left, frenzied, berating an invisible stranger. No one else seemed to notice, in fact, no one flinched, though she, too unaware of them, pointed in reproach, now her voice gruff with vexation, frustrated by an uncompliant accomplice. "What are you doing?" the air, she threatened. She, in her chattering disordered bubble, they on the normal train everyday, went about ignoring eachother. And I looked down into my grammar book and stared at these first sentences:
日本は豊かで安全な国です。
日本人はたいてい親切でやさしいです。でも、ときどきやさしくない人もいます。
"Japan is a rich and safe country."
"Japanese people are usually kind and warm-hearted. But some of them are not."
The train arrived at the next stop prompting slight activity, sleeping heads snap to and run for the door, and she, quiet jittery allowed people near. The doors slid closed and the train was soon in the dark, the windows reflecting lit faces, and perhaps seeing herself once more there beyond the glass, launched a finger-pointing, foot-stomping tirade, that even the young lady who had taken the seat not six inches from the thin standing performer refused to budge, glance or surprise.
What stood there, in loose striped shirt and crooked black skirt, was something non-, a poor old ranter, standing there a cow, or postbox, another commuter, simply other, take no notice.
I couldn't help but listen closely, wanting to hear her Japanese words, but watched more closely the man sleeping next to her, wondering really what he could be dreaming; though his face showed no answers, he woke suddenly before his stop and stood waiting beside her while she muttered screeching like a springshot schoolgirl in some other place.
