I hate people like that that think just b/c it resembles Jesus or Mary that it's a sign. Might as well carve that image in a log and say "It's a sign!", show it to everyone, sell it and become a rich person. A while back someone had a frying pan with Mary in it. Someone offered several thousand for the pan, it was turned down...
To me it's like, the crinkle in my paper looks like a tree, oh, we better conserve the trees...the paper is telling us something...
If Jesus is going to tell us something it's not going to be like that. I don't believe in Mary as Holy.
