I am amused, but also not surprised: an optometrist who jests about your eyesight due to your provenance (may I call it that, since we share one and the same? well, I shall) does not seem to be the most clear-sighted of individuals. I should like to call her out.
If a Pargiter arrives, we shall go on holiday. (Though there but for the grace of Virginia....)
I should like to see you and your chosen Holmes try, Smith.
