Depends on whether they're wearing shirts.
Depends what he's doing in the photo lol
It might be a secret code that the young man has a friend.
Maybe but then again maybe not as I posted a pix on one site and the only one I had at that moment was me and a friend of mine standing next to eachother at a metal detcting hunt so unless ther is anything to really suggest something specific then just another pix.
only if he's started redecorating his room while wearing pink construction books and hummimg the YMCA song
