These all are in third person simple present which confuses me. According to many, the simple present tense is used to describe more permanent actions while the present continuous/progressive tense is used to describe temporary acts. All three of the examples are temporary. James wouldn't rub his neck forever, only while speaking, and so on, which means that they should be in progressive/continuous tenses instead, but that just confuses me.
Rubbing his neck, James speaks.
- This one, for one, just changes the implications. Now James speak forever, according to how simple tenses function, which means it still needs to be made more continuous/progressive.
The rest looks all over the place (if that wording makes sense to describe the confusion).
Rubbing his neck, James start speaking, "Blah blah blah."
Looking out the window, James is thinking about the implications.
The conundrum causes James to be thinking about it.
So what am I doing wrong here in my line of reasoning? I've read alot about present tenses and they use simple tenses to describe almost every action but that seemingly goes against the rules(?) of how simple tenses are meant to be used. I just don't understand this and other similar questions are of no help.
