Aha! That explains why the commission I just got for a pyrographed rat on a cheeseboard ( www.scorchpyro.co.uk for pyrography stuff) had to be delivered by yesterday! I did wonder, especially as it wasn't for a birthday, but it had to be by that exact date, and it was with a rat, not the more usual mouse. Now I know!
I guess the lady didn't fancy explaining that there was such a thing as Rat Day...
