一段时间以后，一个持枪者进来了，把他的电话交给我，“你有很多支持者”，他说。

Some time later, a gunman entered and handed me his mobile phone.

我对自己有个不成文的要求，既然有人花时间给我写信，我就应该出于礼貌给他们回信。

I had an unwritten rule that if someone took the time to write, I would give the courtesy of an answer.

所以请意识到支撑结构已经出来了，并且正在进行,如果需要帮助，如果在课堂时间有任何不懂的问题,请在help@cs50，net上面给我,留言。

So realize the support structure is now in place and in progress so do just let us know at help@cs50.net if you have questions that can't be addressed during office hours.
