A statue of the Virgin Mary in some church in the Sacramento area is crying tears of blood.

Can I just say something before we all get carried away?

When I take a shower in my bathroom, and forget to turn on the fan or open a window, the walls (which are painted yellow), "bleed" red.  Not a lot, just a little.  This is not a cosmic message.  This is the product of paint and condensation.

And this is being generous.  There are, quite likely, other reasonable explanations.
