QUOTE : Thus when Hiroko came up and said, “Nadia, this crescent wrench is absolutely frozen in this position,” Nadia sang to her, “That’s the only thing I’m thinking of— baby!” and took the crescent wrench and slammed it against a table like a hammer, and twiddled the dial to show Hiroko it was unstuck, and laughed at her expression. “The engineer’s solution,” she explained, and went humming into the lock, thinking how funny Hiroko was, a woman who held their whole ecosystem in her head, but couldn’t hammer a nail straight.
