Middle-agedless
The smartly-dressed, young woman having her black leather shoes kissed in this scene may be faceless to us. But at least she’s not middle-aged – unlike the anonymous, faceless and middle-aged, head-in-the-wall footslave.
See how he means nothing to her, as she is fully engaged in a conversation with a fellow female whilst he pays lowly labial homage to her footwear. He’s just a dumb, sexually unappealing, middle-aged footkisser, as far as she is concerned. His middle-agedness makes him an inferior being vis-a vis her youth and (presumed) beauty. He is, in effect, ‘middle-agedless’ i.e. a middle-aged nobody, fit only to kiss the feet of his youngers and betters.
And hopefully it will be the turn of the girl in the bright purple dress and nude peep-toe shoes next!
