Once again, I stared at him: only this stare was different from those other stares. A man was pressing me to do something I did not want to do, and pressing me in a manner he would never have applied to another man: by telling me that I didn't know what I wanted [...] It was as though an invisible membrane had fallen between me and my lover, one fine enough to be penetrated by desire but opaque enough to obscure human fellowship. The person on the other side of the membrane seemed as unreal to me as I felt myself to be to him [...] the memory of that fine, invisible separation haunted me; and more often than I like to remember, I saw it glistening as I gazed into the face of a man who loved me but was not persuaded that I needed what he needed to feel like a human being.
