I was at Whole Foods late last night (yeah, I know – mock if you must) and they were playing Mozart! It was the middle movement of his string quartet no. 4. In my excitement, I may have said “Köchel 157!” out loud. Possibly. But I wasn’t by myself, so I didn’t look as silly as I might have otherwise.
And the cashier couldn’t remember the 4-digit code for my greens, so she gave them to me for free.
(And then I went home and bought opera tickets. Falstaff and Cenerentola, here I come!)
