Было бы проще, конечно, если бы Вы привели пример (ведь в задании сказано: ДИАЛОГ В УПРАЖНЕНИИ ВАМ), но я попробую и без этого составить. Допустим:
Student A: Hey! Do you want to go out for a walk in the mountains at the weekend with me? It will be awesome!
Student B: I doubt that I will like it...
Student A: Okay ... What would you like to do on the weekend?
Student B: I would rather stay at home. I would watch a film and then have dinner.
Student A: That sounds boring.
Student B: I would like to watch a horror film and eat pizza. Are you sure this sounds boring?
Student A: I change my mind! That sounds cool. Can I join you?
Student B: Yes of course. See you at the weekend!
