In this picture, I find the diversity in anticipation.
And yet to have this picture taken the way it is taken, you need things to fall in place. You need the two people in blue (they do stand out, don't they!?) to look back for their friend. You need the ladies in frnt to be lookng for something in the bag. You need that bored looking man in dark grey. You need the little girl in red who is loosing patience. You need all the folks on the left to all be in anticipation.
And that is life. Sometimes things just fall in place. All you have to do is click. So click whenever you can.
