After teaching Chinese eight hours each day, I would head off to the University of Virginia in the evenings to study English. I told the teacher nothing really registered until the second hour--my brain needed the first hour to "reprogram" itself.
白天教八個鐘頭中文，到了晚上又去維吉尼亞大學念英文，我跟老師說，頭一個小時我的腦袋得「換程式」，第二個鐘頭我才能聽進去。
