臺灣籍旅美老師今天交給我們的句子是：

These obsessions are typically intertwined with compulsions — repeated actions. The person has to do just to function. If someone is obsessed with germs, they might wash their hands over and over, even after they logically know that they are clean.
這些執著的行徑通常和強迫行為相互交錯，兩者的共通點便是：當事人一定要一直重復做某些行為，才能夠過活。假如某人對細菌很執著，就可能會一再地清洗自己的雙手，即便理智上明知道自己的手是干凈的。
