As usual, Yingwen, nicely stated. Have a great holiday.

By the way, here's a question to test your cultural awareness. In the office of the college where I work, there are two pairs of scissors - well, there used to be. Now there's one and a half. The half pair has only one handle, which of course, makes it completely inoperable. Now the half pair has been there for almost a year. So, here's the question: Why is it still there? There are four Chinese office workers in the office. One is a student helper. The office is where teachers, Chinese and foreign go to print lesson plans etc. The Dean's office is two doors down the hall. Some of we foreign teachers are curious about how long the half pair of scissors, in plain sight, will remain; so, I guess the question has two parts - why is it still there and how long will it be there?
