I don't get it.  Lately Jessica wants to hang out with me all the time.  We're talking 24/7.  Not that I mind - she is my twin and my best friend, after all.  But it's starting to get a little weird.  The other day she even asked if I wanted to wear matching outfits to school.  I mean, we haven't done that since we were in fifth grade . . . what's going on?
