本来《与亲爱的人去看电影》系列已在网上全部贴出后，就圆满结束了。但，在现实生活中，相关的故事又有了发展。为体现其完整性，就有了这个“后记”。
关于电影《The Theory of Everything》，我和孩儿他爹之间有了一个“走题”的争论，即：气管隔开后，霍金和人交流的小板子和后来的说话机器有没有关系。当时俩人争执不下，老公掉过头，“悄悄地”向儿子发出了“救命啦”的Email。求救呼叫已过去一个多月了，上周得重流感的儿子刚刚恢复了精神后，很负责任地回了信。这个短篇“后记”主要的一道菜，就是他们爷俩儿的Emails （按时间前后，由上到下排列）：

I watched the movie “The Theory of Everything“ with Mom and then run into a big argument with your always right Mom. Can you watch it and support me with my conclusion that the little board to help Dr. Hawking with his communication with others, after his open trachea surgery, has nothing to do with the voice machine he later used in the movie? I want her to be totally wrong this time. Hahaha.

just finished watching the theory of everything. what was the question you had for me?
this is a sample of the system that he uses to communicate now:
Cranky's Alphabet Board
Stephen Hawking’s Computer
he moves his cheek to confirm a selection
in the movie he still had control of his fingers so he clicks with his fingers
the color board he started with uses the direction of his eyes/eyebrow to select letters, and the listener uses the color to confirm.

the underlying principle is the same: the listener/computer says/highlights a letter/word/phrase in a cycle, and the speaker confirms the letter/word/phrase by some movement.

in the movie the 小板子 is used a bit differently. Stephen is using directions of his eyes to speed up the process and the listener doesn't have to say/highlight the word.
see below the picture.
he moved his eyes to the lower right for the red corner (stuvwx) and then middle up for yellow, which is the letter T.

到此为止，有兴趣的网友一定会对霍金的交流工具有了一定的了解。但对这个节外生枝的故事的起因，是我这里想请太太们好好反省的。我的经验教训是，太太尽量要学会说，“哦，不清楚耶。”不然，弄不好就会让俩人陷入不清不楚地囧地。不但费了脑子还小伤了感情。
