I don't understand the explanation for the blue ones Nor one of the purple ones
I'm persevering but think it's far too American for me. In The Canterville Ghost (1887), Oscar Wilde wrote: "We have really everything in common with America nowadays except, of course, language."
The first purple I only got because of a precision selection game my children had years ago. I didnβt understand the title of the blue, but fortunately they were the last four words.
