Another brilliant one. You've a knack for capturing expressions that is truly a gift. What you have here is amazing. And I agree with Jude, it is made all the more potent by just having the "stop" visible.
I think this one says so much in its simplicity. From the solemn look on her face .. to the sadness in his. The slight difference is in the knitting of his brow... I can almost feel the tears behind his eyes. How perfect that he holds the sign that simply says Stop.
