Do I Dare?

I've thought about getting a tattoo (good thing my mother doesn't read this).  The problem isn't so much having something permanent.  It's what design to choose.  I'm one of those crazy people who actually likes change.  I've painted almost every room in my house twice, and I've only lived in it for seven years.  I change my hair color, my nail polish, etc.  How could I possibly pick just one design for a tattoo?

Well, this could satisfy my short-term urges.  Tattoo pens!  They last for about seven days.  And they include stencils!  This could be fun ...
