Ignorance Is Bliss
The pretty customer-mistress pretty much ignores me as I dutifully lickshine her wedged sneakers out on the street - which is bliss, because it means I can surreptitiously study her purple socktop whilst I lick. I fully appreciate what a privilege it is for the likes of me to witness such a beautiful socktop on a customer's shapely ankle, so I make sure to continue to study her socks even as she departs.
Pure bliss!
