I love this photography series called "Touching strangers" by Richard Renaldi. It really challenged complete strangers comfort level to just touch someone they didn't know. The project exposes how intimate people can allow themselves to be and also how hesitant. My favorite is the photo above with the two men in front of the neon green wall. You can see the guy's discomfort in just putting his arm around him, his balled up hand refuses to really touch him. so telling. awesome idea.
