Answer:
Because the host discovered it was futile to keep talking with the guest.
Explanation:
This is a very common behavior after the subject identifies a strong limitation between dialogue. It points out ignorance or the lack of ability to observe a phenomenom from a different perspective. Therefore it is very difficult to create a debate without any bias between both. It is frustrating because the person unable to analyze the phenomenom from another perspective will die to let you know that he or she is correct. But it is because of his or her inability to see the event far away from his or her centered point of view.
This is exactly like comparing a book to a movie - Except there is no visual stimulation with the sound.
I also can't help much - Considering I do not pursue the text. Try to find examples based on my explanation.
Listening to sound reading always affects the way you interpreted the scene during the silent reading - Mostly because there is stimulation of how you are SUPPOSED to feel during this exact moment. The intensity in the narrator's voice, each sound they make, it stimulates your imagination. A sound can make you think differently of a certain point in the text after you read it. Sometimes, the words may sound better when pronounced, too.
Even though, reading may help you perfect your writing, considering you will know how to write words better after seeing them. Writing takes years to perfect, and so does grammar, but by reading you can make it even better than before.
Not only that, but your imagination and interpretation during reading are always your way, and they will change if you listen to it.
I hope I helped! Kudos.
