On Body Decorations: Chris Brown and Spiders

Or what I have come across today while surfing for stories.

First, Chris Brown appears to have a tattoo of a battered woman's face on his neck, at a visible point.  Is this to serve as a warning signal in cultural exchanges or what?  Is it a sign of remorse?  Or an angry challenge?  Or what?

And do we care?

Second, here's a lovely body decoration demonstrated by a male spider in Australia while he woos his sweetheart.  The decoration clearly has a social role in that case.

I put these two topics together for no other reason than happenstance.  I went from one story to the other and noticed the odd commonality.  Make of that what you wish.
