In the reference photograph, the guy looked up as if he was busy writing something and his girlfriend interrupted him in the middle of it. May be by calling his name. He was distracted but it seemed he liked it.
It was a still. I made up this story inside my head.
I needed a story to look for a similar one in the library of my experiences.
When the camera lens was on me, I started to imagine myself in a classroom from my college days.
I had a French teacher who was the sweetest. She was extremely good looking and I was mostly distracted during her lectures.
And she taught French for God's sake!
So, I kept looking down and as soon as the boss was about to click the photograph, I imagined her calling my name and I looked up as if I was looking at her.
