When I was a college student in the 90's, I was sleeping off a heavy night before, when I heard a knock at the door. It was about midday. I schlepped downstairs and opened the door, dressed only in my underpants. I heard the word 'Jesus' uttered as the door swung open, but as the majesty of my bepanted figure greeted the two well dressed gentlemen on my doorstep, the talking stopped. We stood there in complete silence regarding each other for 30 seconds. No one said a word. Then at the same time, they turned and walked away, and I closed the door.
They literally thought I was beyond redemption. And in fairness, they were right.
I really wished later on that I'd said 'can I have a pamphlet'. Would have been a good kiss-off line.
