The joy of resignation

Of course you can't win every game of chess, as much as you try. While some games are hard fought, close run or even just plain unlucky (if there is such a thing as luck in chess), there are some games that seem to go downhill at a steady rate. If there is some solace to be gained from playing such a game, it is that resigning often comes as a relief.
Here is such a game. I blundered a pawn on move 13, and then compounded the error by wrecking my position. The major difficulty I then had was deciding exactly when to resign!
