I dont do small talk, and having thought about it, there are several types of speaking.
You've got small talk, which is a like a meandering river, leading nowhere in particular...
You've got One sided talk, as an aspie would do at times, ranting, or holding forth would be correct terms. Also, public speaking would fall under this.
Then you've got the other type.. it kind of blends into small talk, but its not. I dont know if its got a term, but it never seems to be named, and this is the type where two(or more) discuss something practical, or relevant to the existing conditions, or plan for some event, or things along that line.
I dont know what its called, but I decided to refer to it as 'focused talk'.
I find a lot of pervasive elements of daily life have no descriptive terms, and that bugs me!
