"Ifemelu decided to stop faking an American accent on a sunlit day in July, the same day she met Blaine. It was convincing, the accent. She had perfected, from careful watching of friends and newscasters, the blurring of the t, the creamy roll of the r, the sentences starting with "so," and the sliding response of "oh really," but the accent creaked with consciousness, it was an act of will. It took an effort, the twisting of lip, the curling of tongue. If she were in a panic, or terrified, or jerked awake during a fire, she would not remember how to produce those American sounds."
