Normal Rockwell was mentioned in another Russ' thread of today.
Strange, but I see it in this shot too. While Rockwell captured idyllic, bygone Americana, this shot speaks (again, to me) about contemporary America: a single girl, eating alone, no wine or cigarettes, with totally utilitarian, yet totally un-sexy footwear, hairdo and wardrobe, focused not on the food or (non-existing) drinks or (non-existing) company, but on a computer/tablet/phone in front of her and, most likely, (anti) social media. On the other side of that "connection," as I imagine it, someone equally lonely and bored reads her "tweets" about that "fabulous cafe she recently discovered, with fantastic cuisine she is enjoying" and totally envies her.
End of story. Good catch, Russ.
