What’s the difference between a guitar and a fish?
You can tune a guitar, but you can’t tuna fish.
Interesting Fact: Gravel rooftops attract Killdeer for nesting, but can be dangerous places to raise a brood. Chicks may be unable to leave a roof because of high parapets and screened drain openings. Adults eventually lure chicks off the roof, which can be dangerous – although one set of chicks survived a leap from a seven-story building. ( https://www.allaboutbirds.org/guide/Killdeer )
