A small room inside a bay window. A single bed, a table and chair, and a sink. I could manage something larger, with more conveniences, but I could never match the view.

Atop my table is a hollow rock that I keep meaning to smash open so I can see what it looks like inside. All I know is that it is a geode, and its mother is a volcano.

Rocks are not supposed to be hollow. What is the expression -- solid as a rock? But even "hollow" is not nothing. Or so says Hiedegger's jug.
