Sometimes I mind the tame way people hold each other. Here it seems to me that the man is merely lolling around the girl and the girl only has the barest grasp of him, almost as though she's holding just his t-shirt. You can't feel someone the way she is holding him, with her half clenched fist. There is not much lust here. Well, of course there may not have been. I think I will ask them when I see them again. "Are you just friends?"
Anyway, I have promoted this photograph into my favorites list because of her dress, their matching slimness and his pride (or is it challenge?) — the slightly raised chin.
