Duncan lives much of his life as if he's starring in a film. He has an ongoing script that he mutters to himself as he goes along. When he's riding his bike he's really Percy the cheeky steam engine and he crashes into buffers or goes too fast and comes off the tracks. As well as the Thomas Tank stories, an assortment of other characters and scenarios are played out.
Recently he's taken this a step further. In the past few days when he answers me or tells me something, or just is scripting one of his myriad adventures, he puts his own words in quotes. As we walk into the shop together he says, "'Let's go!' said Duncan."
When I don't get him a book he wants, it's, "'You're a nasty woman,' grumbled Duncan."
When he can't get a new Trainz engine downloaded he says, "'Oh dear, it's all wrong' cried Duncan."
At bedtime, when I ask him to turn the computer off and come to brush his teeth, "'I don't want to go to bed,' moaned Duncan."
