Ronald Dahl knows magic.
He has an intimate relationship with it. Maybe he even is
magic. As illogical as all this sounds, it's the only logical explanation as to why he can create such fantastical and whimsical stories that, technically, should make rational people want to pull their hair out saying, "No, no! Such a thing cannot happen!" and instead makes them smile and say, "An elevator through a roof is completely
rational." It's the only way to explain how rowdy, naughty children - who have the attention span of a blade of glass - can sit for hours on end, listening to the tales he's woven and created. Maybe you could say it's genius, but I say it's magic.
