Anne told Peter that he has an inferiority complex. She wrote this on her diary dated Wednesday, February 16, 1944.
Her diary entry reads:
"After I'd explained some French to him, we began to talk. He told me that after the
war he wanted to go to the Dutch East Indies and live on a rubber plantation. He
talked about his life at home, the black market and how he felt like a worthless bum.
I told him he had a big inferiority complex."
"Peter has a huge inferiority complex. For example, he always thinks he's so stupid and
we're so smart. When I help him with French, he thanks me a thousand times. One of
these days I'm going to say, "Oh, cut it out! You're much better at English and
geography!" "
"Annoyed" is the most synonymous word out of the four. To check, look at the context. The final sentence, "Either way, I did my best to avoid her," allows the reader to infer that the narrator is annoyed by her presence.
