Everyone has bad days, and when you're having a bad day, you think, 'Here I am being singled out by a hostile, malicious universe that is picking exclusively on me.' And then you read a book about bad days and realize they happen to everyone, not just tormented, persecuted you.

Kids are always writing me: 'I had a bad day too.' 'I got gum in my hair.' And the kids also write to me to pass on advice to Alexander. My favorite one of those being, 'The next time you have a bad day, blame your brothers.' I didn't expect this. It's certainly the most successful of my books.
