Commuters on the train into London share certain characteristics. Predominantly they are male and around 40 to 50 years old, the women I do see are younger, say 30 to 40 years. Both are immersed in their work and able to shut out the distraction of the passing countryside and occasional requirements to make way for boarding passengers. Their eyes are motionless, fixed on word processors and documents. I draw them as they work, trying to capture both there stillness and concentration. they never look up at me, they are oblivious of my scrutinising glances, I am invisible.
