My sister cracks me up all the time.  Today, we were talking about how insane Twilight fans can be.  I told her of a thread I read once where women were showing off their Twilight tattoos.  This led to a discussion about Harry Potter and how she could understand people being more fanatic about that book because it was better written (even though she is a Twilight fan, too).  This is the discussion that followed:

Sister: I’m a huge Harry Potter fan, but I still wouldn’t get a tattoo.

Me: Don’t lie.  You know you have a lightening bolt on the small of your back.

Sister: No, it’s a snitch and it’s on my butt.

My sister is awesome. : -P
