The speaker was obviously meaning to say “every cloud has a silver lining”, but where did the tree come from? Possibly he was thinking of a silver maple, those messy trees that every yard seems to have. Or, as my “ol pal” suggests, the word “sliver” instead of “silver” floated up in the brain soup, suggesting wood. “Barking up the wrong tree” also might have been in the mix, even though the meaning is not remotely close to the intended meaning. Any other suggestions out there? Thanks to Art for sending this one to the site.
