I didn't even catch that it was his hair. I just thought he had a preverted smile in because he liked the uke's face. That's what usually happens............ so it was his hair............. I guess that makes more sense.
I guess it's just one of those illusions that some people see one picture, some another, and a few, both pictures. Does anyone know the kind I'm talking about?
I stared at his fucking face about 5 minutes thinking it was a fucking smile but it was the uke’s hair curl
