One day when Lotta on Troublemaker Street had just turned five she woke up one morning already grumpy. She’d dreamt something she didn’t like and Lotta thought that what you dreamed was true. That’s why she was cross with her siblings, because it was them she’d dreamt about. And then along came mummy who wanted her to wear an itchy, prickly jumper. A day that begins all wrong like that couldn’t possibly turn out nice, could it?
