A Susan has been walking back and forth outside the operating room since 10:00 o'clock last night. She left for a while to get
coffee from the vending machine and continued walking back and forth again, with her coffee and her cellphone in her
hands. By 2:00 in the morning, she received a call. After receiving the call, she started texting Mr. Edgardo, informing him
that she could not go to work today until the next day.
