“I just noticed this strange X shaped thing on my roof. I have no idea what it’s made of. It has some sort of a hinge or a clasp in the middle. Any ideas?”
Answer: "It’s a part of someone’s rooftop antenna. It’s likely that it blew off from somewhere during a storm."
Could it be the picture is upside-down?
"Tastes like lime..." I'm more concerned that the person would taste something that they don't know what it is (the answer is probably correct but still...)
