'I know Michael is definitely looking down on me - I want to do stuff he'd want to see me doing, I want to make him proud'

After he has painted the most beautiful and authentic picture of his brother during a heartbreaking yet inspiring hour, I wonder why Alan O'Sullivan doesn't appear to be angry with the world.

"What am I supposed to do?" he says. "Lie down and cry about it every day? I'd rather go out there and make Michael proud of me. I want to do stuff that I know he would like to see me doing. I want him to be proud of me. He's looking down on me. I wouldn't be the most religious person in the world, but I know he's definitely looking down on me."

Michael's younger brother has every reason to be raging with the world. Earlier this year he lost his partner in crime, his best mate. The one he kicked a football with out in the back garden; the one he rode races with on the arms of the couch; the one he wrestled with; the one he argued with; the one he hugged; the one he played tricks on his parents with; the one he rang after every race; the one he spoke to every single day without fail; the one he idolised.
