I now this lady.It is by no means her first visit.Her daughter,Nicole,bought the house net door last October. Nicole,who is currently in Shanghai,has apparently told her mother that I am having heart surgery shortly,and the result is that her mother has decided I need to be supplied with meals. I now what is inside the paper carrier bag-a stainless-steel container with a meal of rice,vegetables and either chicen,meat or shrimp.This has become an almost-daily occurrence. Communication between my benefactor（恩人）and me is somewhat handicapped by the fact that she doesn't spea English and all I can say in Mandarin is "hello".Once,she brought an iPad and pointed to the screen,which displayed a message from Nicole telling me that her mother wanted to now if the food was all right. "Your mother just can't be bringing me meals lie this all the time,"I protested.“I can hardly reciprocate by cooing something from my native land,lie roast beef or Yorshire pudding for her,”I said. "Oh,no,"Nicole said."Don't worry about that.She has to coo for the family anyway,and she wants to do it for you.You can call her Wing,which is her surname." The tenant in my basement suite is a university student who speas Mandarin quite well,so with her help,I have found out that Wing is 68-13 years younger than I am-and that she lived through the Cultural Revolution.For my part, I was raised in wartime Britain. So here we are,two grandmothers a world away from where we were raised,neither of us able to spea the other’s language.But the doorbell eeps ringing and there is the familiar paper carrier bag,handed smilingly to me by Wing. Right now I am woring on some more Mandarin words-it's the least I can do after such a display of indness. "Than you"is,of course,the first one,which somehow seems inadequate.

Faceboo recently admitted that nearly all of its 2.2 billion users have had data scraped（篡改） by “ill-natured” people or companies. The firm itself has joined calls for better privacy（隐私） regulations. For years, watchdogs have been warning about sharing information with data-collecting companies. Most casual internet users are only now realiing how easy and common it is for irresponsible and unnown organiations to collect detailed digital data of them. They do this by combining the separate bits of information consumers have given up to e-tailers, health sites, qui apps and countless other digital services. A study from researchers at the University of Queensland shows that staying off of Faceboo for five days can actually lower levels of the stress in the body. Yet despite the study, and the recent DeleteFaceboo movement, Faceboo user statistics remain strong. As scholars of public responsibility and digital media systems, we now that the business of social media is based on user data and offering it for sale.
