Jon looked down at himself.
Nothing had changed. Not a thing.
Wait a minute! The badge on his pink mini-dress no longer read 'Karen'. It now said 'Shelly' instead.
Yet again loose wishing had screwed up his day.
"Okay." he began "When I wished to not be in Karens waitressing outfit this isn't quite what I mean't."
He thought for a moment. Carefully. The sounds coming from beyond his hiding place indicated that it wasn't going to be a hiding place for much longer. His Mum already seemed suspicious about the strangeness going on around the place and he had to sort out this clothing thing with his next wish or he'd be coming out of the 'transvestite waitress closet' to the entire kitchen staff.
Again.
It's tantamount to Jon's shellshocked state of mind that he didn't simply wish himself into his bedroom. And perhaps fortunate too. There's no telling if an innocent wish like that wouldn't have been twisted by the rock into trapping him in his room forever.
"I wish I was in my own clothes and that no-one would think there was anything strange going on - particularly Mum."
