Susan became part of the group. This is the third of six Strangers who are more or less related. While I was speaking with Dave, Susan came up and began speaking with Al. She smiled the entire time, and I assumed that they knew each other. Not so.
So during a lull in their conversation, I asked if I cold photograph her. She did not resist, but was shy, and seemed kind of embarrassed. I got several shots, all of which looked like this. In fact, that's how she looked while in conversation with Al too.
