We can be friends anyway, can't we? Why was the speaker worried that they might not be friends?

After Annika tells Pippi that it is wicked to lie, Pippi goes on a long tangent about her reasons for lying..... a long, fictional story. She end her story by asking if they can be friends even though she occasionally lies, as it isn't really her fault.

"It's wicked to lie," said Annika, who had at last gathered up enough courage to speak.

"Yes, it's very wicked to lie," said Pippi even more sadly. "But I forget it now and then. And how can you expect a little child whose mother is an angel and whose father is king of a cannibal island and who herself has sailed on the ocean all her life -- how can you expect her to tell the truth always? And for that matter," she continued, her whole freckled face lighting up, "let me tell you that in the Congo there is not a single person who tells the truth. They lie all day long. Begin at seven in the morning and keep on until sundown. So if I should happen to lie now and then, you must try to excuse me and to remember that it is only because I stayed in the Congo a little too long. We can be friends anyway, can't we?"
