Even if people do wrong, we're social animals, so what can we do about stopping them doing the same things in future? Saying people are 'bad' or 'evil' is just an unwillingness to engage an unwillingness to try to empathise. That sanctimonious attitude doesn't help anyone.

In the 'Garnethill' trilogy, people always forget that Maureen O'Donnell's dad was a journalist and she did art history at uni and her brother did law, but no-one ever thinks they're middle-class - they're just working class because they speak with accents.

Comics don't work if the story is all in the text and the images are illustrative. It's hard to have enough faith in the artists to allow them to do their job.

We don't really go in for big family dinners, but Scottish people are famously confrontational. It's a cultural thing, so maybe we don't need to have them to clear the air. Also, traditional family food isn't as nice here so there's no payoff for traveling hundreds of miles.

I love Mikhail Bulgakov. He is very original and takes the story to unexpected places. I didn't realise political writing could be so funny.

I was very aware of office politics because I was so baffled by them. So much so goes unsaid. No one says 'you're a cheeky so-and-so,' no one says 'you're so moody,' nobody ever confronts anyone else about anything. But I'm very crass, and I'm very confrontational, and I have a temper. I had to be hyper-vigilant in every office I worked in.

I always wanted to work at 'Take A Break' magazine, you know, just to inject a little bit of politics into their stories. I applied for a job there after I'd done my law degree and didn't even get an interview. I only wrote 'Garnethill' because I didn't get that job!

If you went for a job interview in a Glasgow law firm, they used to ask you what school you went to. And that was a way of finding out what religion you were.

In the forensic science course I took at university they used photographs of dead bodies. For ballistics they showed us a guy lying on the floor, and his head had burst.
