I don't change the language for children books. I don't make the language simpler. I use words that they might have to look up in the dictionary. The books are shorter, but there's just not that much difference other than that to be honest. And the funny thing is, I have adult writer friends [to whom I would say], "Would you think of writing a children's book?" and they go, "No, God, I wouldn't know how." They're quite intimidated by the concept of it. And when I say to children's books writers, would they write an adult book, they say no because they think they're too good for it.

We all are [normal]. Their idea of normal just happens to be different to some other people's idea of normal. But this is the world we live in. Some people simply cannot accept something that is outside of their experience.

The thing about exploring is that you have to know whether the thing you've found is worth finding. Some things are just sitting there, minding their own business, waiting to be discovered. Like America. And other things are probably better off left alone. Like a dead mouse at the back of the cupboard.

There's things that happen in a person's life that are so scorched in the memory and burned into the heart that there's no forgetting them.

He suddenly became convinced that if he didn’t do something sensible, something to put his mind to some use, then before he knew it he would be wondering round the streets having fights with himself and inviting domestic animals to social occasions too.

I like the idea of standalone novels. I always found with series of books, it's something that publishers love obviously because they can make a lot of money and they build an audience from book to book, but I don't like that as a writer. I prefer the idea of just telling a story, completing it within your book, and moving on and not forcing a child to read eight of them.

I don't buy into the idea that an Irish writer should write about Ireland, or a gay writer should write about being gay. But when I found the right story, I saw it as an opportunity to write about being a teenager and being gay. Most people, whether you're gay or straight or whatever, have experienced that relationship where one person is much more interested than the other.
