I have the following exercise in my textbook:
So, Matt, how are things with you? You look very well. I hear you (do) OK for yourself.
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 do, one of the present simple and present continuous or both.
Only the present continuous can be used here, according to the textbook. I have absolutely no idea why.
Here, do seems to be a stative verb. It is used to describe what the other person is. He “is doing OK.” Why would one want to use the present continuous here? And why is the present simple not appropriate here?
