I quickly grabbed this shot as I pulled up to a stop sign, and this young man looked like he was an outcast, not a part of the playing crowd. Hopefully he was able to join in on the fun before recess ended.
Heartbreaking, if as you say, he was shut out or ignored. But, as others have suggested, if he chooses to go his own thing, it is a great picture in contrasts.
I love the way you processed this, Rick. It shows that this kind of behavior is timeless...kids will always leave someone out. The way his head is bent shows he is deep in thought.
