I once played perfect in a perfect match in a perfect tournament.
It was a long time ago in a place on the other side of the world. My first thought about what you might say is, "Come on, really?" I say that to myself all the time, but it really did happen. And, as a pretty good rugby player in my day, I made a point of striving for perfection every time I played. So much so that unfortunately I seem to remember all the times I was -not so- perfect.
