Our reading
An editorial interpretation.
A seller laments a lost deal with wounded self-pity. The speaker insists they could feel the sale coming and were working at peak form, so losing it feels like a personal injustice. The comedy lies in the grand sense of destiny attached to an ordinary transaction.
