Eileen has problems with sayings. She likes words to do their job properly and for their meaning to be obvious. It took her a long time to get used to innuendo, single, double or otherwise and even now "peculiar" sayings such as if the cap fits, wear it, causes her some grief. She assumes someone really is talking about getting the correct sized hat.
Eileen has always considered these to be the Met Office's "best guess" though compared with what the Fairy Kingdom's weatherman came up with, the Earth based ones are full of information and Eileen knows by far which one is the most accurate. In fairness to the Kingdom's weatherman, he has to report on several different layers of the Kingdom's atmosphere, all 7 regions and so the forecast goes on for at least 20 minutes. Eileen prefers the briefer Earth based ones.
Eileen considers this to be a cleverly worded con. She's right.
