本來《與親愛的人去看電影》系列已在網上全部貼出後，就圓滿結束了。但，在現實生活中，相關的故事又有了發展。為體現其完整性，就有了這個“後記”。
關於電影《The Theory of Everything》，我和孩兒他爹之間有了一個“走題”的爭論，即：氣管隔開後，霍金和人交流的小板子和後來的說話機器有沒有關係。當時倆人爭執不下，老公掉過頭，“悄悄地”向兒子發出了“救命啦”的Email。求救呼叫已過去一個多月了，上周得重流感的兒子剛剛恢復了精神後，很負責任地回了信。這個短篇“後記”主要的一道菜，就是他們爺倆兒的Emails （按時間前後，由上到下排列）：

Subject: 救命啊 - Stephen Hawking communication device – 請回答
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.

到此為止，有興趣的網友一定會對霍金的交流工具有了一定的了解。但對這個節外生枝的故事的起因，是我這裡想請太太們好好反省的。我的經驗教訓是，太太儘量要學會說，“哦，不清楚耶。”不然，弄不好就會讓倆人陷入不清不楚地囧地。不但費了腦子還小傷了感情。
