Would you be kind enough to tell me whether I am right with my interpretation of the expression in bold in the following sentence?
I should have been no true friend to you if I had let you on this fool’s errand. (Haggard’s “The Witch’s Head”, chapter IV)
a fool’s errand = a hopeless affair
Thank you for your efforts.
More or less, though errands are usually short undertakings, going to get something and then coming back, for example, whereas affairs are ongoing business, much of the time.
