Apparently in my world, there are two 13th of Decembers. My sister told me about the Spicks and Speck-tacular show in Wollongong, and I thought "Why not?" and bought tickets. I already knew that date was taken, but when I mentally checked the date, I counted forward from the beginning of December, instead of backwards from Christmas, which would be the file my brain shoved that other event in.
So, if anyone knows someone who would like to buy a pair of tickets to the show (and who doesn't know Mim & Adam), please point them in my direction.
