It's no secret that Martin is a little OCD. Or CDO. It's like OCD but the letters are in alphabetical order ... as they should be.
A little compulsive disorder humour there but seriously, his OCD is serious.
Everything at his desk must sit at a right angle. (One of Sarah's favourite things to do is to slightly tilt his computer screen when he's out of the studio; drives him nuts).
When he hangs out washing, any pegs used on a single item must be the same colour.
He checks the doors are locked at least five times before he goes to bed at night and this week he revealed that he has what he considers "his park" at the supermarket ... and the video store ... and the sports park. Basically anywhere there's a carpark, there's a "Martin park".
