On Monday, I was traveling in the train

There came a guy looking decent & plain

Right in front of me, his seat was given

But he never did come in my central vision

He wanted a conversational outburst

So he tried to catch my eyes first

Instead, he was only in my peripheral vision

But now he is the source of my inspiration

For your information :-

Peripheral Vision - all that is visible to the eye outside the central area of focus i.e. side vision

Difference between peripheral and central vision:

When you read a word on a page, you are using your central vision, but it's your side vision that tells you if the word is at the beginning or end of a sentence, or at the top or bottom of a page.
