It's actually a art project or something, they are statues. Isn't it awful? lol
Reminds me of a story my auntie experienced. A religious women, she likes to church hop. On a morning she visited the area's cathedral with nobody but herself and a woman in the front row. Like any catholic, you knee towards the alter upon entering and exiting, So, she walk to the front to knee before the alter. For a while, she prays. To acknowledge the woman's presence, she said, "God be with you". The woman smiled, got up, and as she walked down the aisle she became less opaque. Then my auntie stay to prayed harder.
