I have the following exercise in my textbook:
I can’t complain. I (run) my own consultancy business.
The context is “. . . conversation between two ex-colleagues who have not seen each other for some time.” It is asked to use the appropriate tense of run, one of the present simple and present continuous or both.
Both tenses are valid, according to the text book. Why is the present continuous valid?
Here, I think “run” is a dynamic verb. It is used to describe an ongoing action. Why, then, the present continuous? The activity of “running . . . business” hasn’t started at the time of speaking. The speaker doesn’t seem to suggest it is or may be temporary.
