Grapes of Regret

This year the grapevine in the garden fruited more heavily than ever. In the first year I noticed it (I can't believe that was the first year I came here, but perhaps it was) I got a couple of small bunches of edible grapes off it, and, since then, nothing. But this year, this year, there were festoons of grapes, a couple of dozen bunches at least. This was the one with the biggest, roundest, most enticing-looking grapes, so I used it as a test.

The grapes were vile. Almost inedibly sour. I left the rest to the birds, as they seem to like them.
