If a man (who is obviously taller) hugs a woman, whats the difference between these two?
Guy hugs the girl over the shoulder: that way her hands touching his middle back, his arm are over the girl's shoulder/neck, her face touching his chest area.
Guy hugs the girl under the shoulder: that way he bends down, he holds her middle back, their face cheeks are pressing to each other, her hands are on his shoulder area.
