David Mortimore Baxter has a terrible problem - he can't stop lying. So here's the thing. I didn't want to go to rose Thornton's house for dinner so I pretended to be sick. But I wasn't sick. And Mum found out. Now Mum's so mad with me she's thought up the worst punishment ever. One more lie and Boris is going to the pet shelter. So that's it. I'm turning over a new leaf. But if Mum hates it when I lie, she's really going to hate it when I start telling the truth.
