Facial expressions...

... can be the making of a street photo for me. 

That's especially true when, as here, there is such a contrast between expressions in the same photo. Fortunately, moments later, everything looked perfectly normal again. I suspect the lady had been studying a street map or directions.

My extra seemed to sum up the uncomfortably cold weather conditions this morning. It was so cold that, in this case, we can only guess what the facial expression was like.
