一定係隻耳仔生係C忽度 - no, may be she couldnt even really understand ENGLISH, becoz she's come from 阿公度 , 驕, next time when you talk to teacher, and also that "smart" woman is around, u should remember to bring a 大聲公 with u and repeat it in Mandarin once again in front of her. Coz I doubt she even couldnt understand Cantonese 呢!
