How would you explain this sentence?
"Andele. Go on now, get in the water," he said. "You will be surprised."
The pale-skinned boy stood shivering in water up to his waist, thinking these were the most awful words in any language: You will be surprised. The moment when even-thing is about to change. When Mother was leaving Father (loudly, glasses crashing against the wall), taking the child to Mexico, and nothing to do but stand in the corridor of the cold little house, waiting to be told. The exchanges were never good: taking a train, a father and then no father. Don Enrique from the consulate in Washington, then Enrique in Mother's bedroom. Everything changes now, while you stand shivering in the corridor waiting to slip through one world into the next.
