Which conclusions were you thinking of particularly?
Not any particular conclusions, but all of them, in general.
Your topic is communication through speech.
The written word, IMO, is an animal of completely different stripes.
You yourself know that written words can be misconstrued if the thoughts aren't conveyed properly or thoroughly. Look at our initial meeting as an example. I misconstrued the conversation initially and yet here we are conversing with a better understanding of each other. Facial expressions and intonation might have precluded such a misunderstanding.
Aside...I have devolved over time in my replies, despite the length of this reply. Fewer words in an effort to be more concise...sometimes to my detriment as I don't manage to get my point across.
