When Dr. Davis began asking questions, Alice was confident in her ability to sail through it because remembering an address is something she’s never had trouble with in the past. She takes for granted the idea that she can recall such a simple thing without actively trying to keep it in her mind, which accounts for her bewilderment when Dr. Davis asks her to repeat it and she finds she only remembers half of the address.
