Easy peasy.

Today's Blip leapt out at me.

NOT a pretty sight if I'd answered the door starkers.
Grabbed handy bath robe and answered said door; having been duly summoned by a rendition of "Für Elise" on the doorbell; unfortunately not it all...
;¬)
Almost out of sight was a waiting postie, just be sure the door was answered.
THIS is what I saw.
