Every once in a while, you see stories on the news that an image of Mary, virgin mother of Jesus, appeared on the side of an overpass, in a rain puddle, on a grilled cheese sandwich. Here's my question? Why do any of these people think they know what Mary actually looked like? Do they think that the image looks like an artist's representation they've seen of Mary? Or do they just go, "Woman: check. Headscarf: Check." Case closed. It's the mother of God.
My guess it's because a grilled cheese image of "Little Red Hiding Rood" wouldn't go for 2 million bucks on eBay.
