I don't know. If the girl was with someone, they'd have their friend shoot them, or selfie both of them. In any case, I'm talking about people who look like they're really all alone, on vacation traveling or whatever. I enjoy offering to take their pictures. Often, when there are a number of people like a family, and one parent is taking shots of the rest of the family, I offer to shoot all of them. I do my best to really get a memorable picture and it's much appreciated by them. I feel good about it too.
