雅思口语P2 Describe someone who is talkative(文字版）

I happen to know a lot of people who like to talk a lot, but today I would like to tell you about one of my closest friends, Jason. This guy is extraordinary, he never rests his mouth. He can cover all kinds of subjects, and has no sense of transition. He can talk about politics, and talk about his girlfriend two minutes later. This personality of his can be very handy in some situations, and less in some others. For example, he has to be present in all parties of ours, because you are sure that he will put us all in a good atmosphere. He is pretty joyful and knows how to cheer people up. On the other hand, I must be honest, he can be very annoying. There are times when one just wants to rest or concentrate, but this is impossible when he is around. He will start talking and will never stop. I remember one time when I had to work on a research paper for the next day, and so I needed all my concentration to complete the task. But Jason came to my house because he was nearby, and started telling me about his day, and even though I told him that I needed calm and peace. So I wanted him to leave. This can seem heartless from another perspective, but we are very good friends so this is nothing to us.
