Charlotte would always answer when spoken to, taking the lead in replying to any remark addressed to both; Emily rarely spoke to any one.

Charlotte's quiet, gentle manner never changed.

She was never seen out of temper for a moment; and occasionally, when she herself had assumed the post of English teacher, and the impertinence or inattention of her pupils was most irritating, a slight increase of colour, a momentary sparkling of the eye, and more decided energy of manner, were the only outward tokens she gave of being conscious of the annoyance to which she was subjected.
