Sorta like a psychological test meets a photographer: 'Touching Strangers', by Richard Renaldi, is a series of photos where, yep, strangers are touching. Some are awkward, some aren't.
I was trying to think what I would do if I was asked, and I've come up with: I would completely embarrass whoever I was taking a picture with, try and get the craziest expression out of them (like jump in their arms unexpectedly)...that way I look like the normal one! Crap...did I say that outloud? via
