The way I talk to the puppets is real, and it's in the moment, and it's seeing what will happen. It's not something that is scripted.
Having a puppet is a way of having opposing opinions - I say a thing; he says the other.
I think I've got it pretty easy compared with somebody who works at a desk nine to five. I'm just working for an hour in the evening. I get a bit breathless, as I have to talk non-stop because of the puppets.
I could never be on stage on my own. But puppets can say things that humans can't say.
