4: We can also use the present simple for short actions that are happening now. The actions are so short that they are finished almost as soon as you've said the sentence. This is often used with sports commentary, or in demonstrations.
He takes the ball, he runs down the wing, and he scores!
First I put some butter in the pan and turn on the cooker.
Here is a scene in a movie.
A: We should end our relationship here
B: Fine
C-a friend of both A & B, has just passed by & says: Do you guys break up?
A, B & C are Americans
So, does the sentence Do you guys break up? fall into the above use of simple present tense (The actions are so short that they are finished almost as soon as you've said the sentence)?
But I would say it is better if C says: Have you guys just broken up? to mention something that has just happened.
So, "Do you guys break up?" or "Have you guys just broken up?" Which one is better?
