I don't know who of them are you, but i can tell you who you are not:
(assuming that the info on your profile is true, and the photo is true too)
--You are not one of the ladies, as you said you are male.
--You are not one of the three guys in the background, as three are too young, and one too old.
--You are not the white-bearded one, with a beige jacket. Too ordered to be an "ELF". (i Think)
So either you are the one with a red t-shirt and black jacket... Or the one who took the photo.:P
(If you find any mistake in my English, please let me know via a PM)
(Really, I speak terrible English, so please, tell me if I make mistakes. I'd like to improve it a bit )
