Seeing double

Everywhere I go, I keep seeing twins these days.  When I was on vacation last month, I not only ran into a set of identical twins (adult women) but also a set of identical triplets.  The three little boys were blond and so cute.  I saw one and then his twin.  When a third came running around the corner, I just about stopped in my tracks.  Last night when I was handing out candy, I had twin trick-or-treaters.  One little girl was a princess and her sister was a superhero.  It made me think of a little Lexie and a little Roxie, definitely.  Who will I run into next?
