We were tired, bored, uptight, all that. What comes from walking too long in a single city, going up and back every single street, looking up and down every single building. We’d seen every sunrise from every window. We’d taken coffee in every single café and waited patiently at every single stop sign. Which was what surprised us about the drawing of the cavern on the pavement. On a normal pavement, where there had once been just grey concrete, spots of dried blackened gum, flecks of bitumen, was a chalk drawing of a cave, with walls disappearing down towards darkness. We looked at each other as if to say, should we? I felt your hand link into mine, and our knees tensed, each waiting for the other.
