Answer the question about text:

We were posed this essay topic for English and I was thinking about it , when Lai Lin said that ignorance has no bearing on arrogance and I thought she was absolutely right . She should have shut up there , except that the next day , she returned and was like wide- eyed , epiphany and said , " I ' ve found what connects arrogance and ignorance ! " Obviously , I got excited and asked her what , but Lai Lin is Lai Lin and she is mongoloid .

Why is Lai Lin so excited about the lesson .
Lai Lin feels that it offers proof she knows English .
