Not all shoots are created equally.  With some shoots I have to use every trick in the book (you need quite a few when photographing kids!), with other shoots the fun and joviality unfolds naturally right in front of me and all I have to do is click the shutter.  This was one such shoot.  Easy peasy.  Not only were the laid-back parents happy to hang back and entrust me with their children, but these two gorgeous sisters were just SO. FULL. OF. LIFE!  Their energy and enthusiam was so infectious, I found myself skipping all the way back to the car-park hand in hand with the youngest sister!  When she turned to me and asked me if I was a teenager, I think my smile could have been seen from space :)
