Older man

You take a train to your job at a local café, as you enjoy the journey and the train is usually pretty empty.

Recently, you've been seeing an older guy on the train.

He's always reading, and you've seen him go through about 5 books in the time you've seen him.

You never actually thought about it until one day you glance up to look around, and he's looking at you from the corner of his eye.

Whenever you lock eyes, he quickly looks away and clears his throat, and slightly shifts in his seat...
