I really like the perspective of this shot. The slightly skew horizon in combination with the bent backs of the ladies gives me a giddy feeling which perfectly fits the action of bending for an old lady. The opposed backs and the horizon form a great geometry.
It is a fun shot because they happen to do a similar pose at the same time. A small dog involved with an old lady adds comedic elements just on its own.
Therefore I give you the full rating because this picture combines situational humour, an eye for it, lucky incidents and the coincidence of taking a picture in the right moment.
