The English language can be extremely confusing and illogical, especially for people with an autism spectrum disorder (ASD) who interpret meaning in a very literal way. Why should an announcement that cats and dogs are falling from the sky indicate heavy rain? And what have chickens got to do with being a coward? "It's Raining Cats and Dogs" is a witty and stylish insight into the mind of someone with an ASD. It beautifully illustrates why people with ASDs have problems understanding common phrases and idioms that others accept unquestioningly as part of everyday speech.
