This is 'Secret Friends', a photo series by AnaHell in which the subjects are bent over with a face drawn on their back, and wearing wigs sometimes. They are kind of uncomfortable to look at. Sort of like me. I'm not saying I'm a total monster, but I am saying I wear paper grocery bags over my head with different faces drawn on them to reflect my mood. Lately I mostly wear the frowny face one. Except when I sleep, then I wear the one with the eyes closed so my girlfriend doesn't think I'm staring at all night. "Your girlfriend -- the pillow with the face drawn on it?" Shhhhhhhhhhh -- she thinks she's a blanket.
Keep going for a whole bunch more.
