Brick, the finding and marble.

1. Treading on a loose brick in the pavement and hearing it go "collop".

2. I lose Nick while shopping -- a combination of my dreaminess and the crowds. I like to catch sight of his head behind a book display.

3. Ladelling mulled wine into a pair of goblets made from purbeck marble. Purbeck marble is really polished limestone, not marble at all. It's packed full of fossils. Every time I use these goblets I spot something new -- this time, two translucent spots on my goblet distinguishes it from Nick's. The wine was good, too.
