Interesting choice! Dahl wrote quite a few short stories for adults, but of course he's most well known for his children's stories.

There should be no embarrassment for adult readers to read (or re-read) his children's stories. They are a masterclass in writing - full of inventive and imaginative prose. He knows how to write fluidly without excess verbiage. These are qualities we'd all love to have in our writing.

All of this makes his stories very easy to read, but satisfying and enjoyable too.
