on chapter 1 part 2: Describe the incident with the girl in the hall, especially the “surprise. “

The incident

"They were perhaps four metres apart when the girl stumbled and fell almost flat on her face. A sharp cry of pain was wrung out of her. She must have fallen right on the injured arm. Winston stopped short. The girl had risen to her knees. Her face had turned a milky yellow colour against which her mouth stood out redder than ever. Her eyes were fixed on his, with an appealing expression that looked more like fear than pain."

The surprise;

"Nevertheless it had been very difficult not to betray a momentary surprise, for in the two or three seconds while he was helping her up the girl had slipped something into his hand. There was no question that she had done it intentionally. It was something small and flat. As he passed through the lavatory door he transferred it to his pocket and felt it with the tips of his fingers. It was a scrap of paper folded into a square."

Winston thought the message was going to be something political. Instead, ir said, "I love you."
