Wrong
She's not usually wrong.
In fact, this exhibit that she's standing in the middle of—it's there because she was right. About Anok and Meti. It's kind of ironic: she was right about these men she never had the chance to meet while they were alive, but she was so wrong about the person she thinks she knows best.
You see, she thought he was going to kiss her. Thinking back two seconds, she wonders why. Yes, he was standing close to her and looking at her in a significant way, but he's done those things before. Experience says that, between them, neither action foreshadows osculation. Besides, she knows him, knows that he is sexually uninterested in her (which she accepts though it makes no evolutionary sense).
The low, disappointed, self-ashamed feeling that she does her best to rationalize into nonexistence reminds her why she doesn't like to be wrong.
