Oh man, you have such a great eye for a shot with a story! Love how the two older subjects are still/stationary and engrossed in each other, while the younger ones are 'in motion' (running/jumping) and in their own little world. Wonderful juxtaposition of old and young.
Marvellous capture, Tuna.
The stairs provide a lovely pattern as background, the two are engrossed in their conversation and not moving at all, the two young ones jump out of your frame to the left and the right, so there is structure and stillness, talk and expression, motion, age groups ... it is all there.
