daughter hid 罚款 .....

daughter fogot to return books on time, got 罚款, afraid of me, she hid 罚款, so finally we were fined for the max. i took her to the library to pay the fine ($ about 30 dollars), since then, she remembered to return books on time. i didn't punish her, just told her it was stupid not to fix problem on time but made things worse.
