А поимпровизировать? Я конечно диалогами не занимаюсь, но тут такая тема :D
Jack: Hi Dan, I need your help.
Dan: Hi Jack, sure I will help you.
Jack: Last time I think too much about my life and I am not satisfied by state of affairs.
Dan: Oh, what is the problem?
Jack: Today I realized that I am unhappy all the time. I can't go on like this anymore. Answer me what should I do to be happy?
Dan: Well, it is nice question. And the answer is simple- to be happy you should live. We often perceive our life as a burden, you have to forget about it. Enjoy your life, discover, wonder, make friends, love, discuss and you will get lots of good feelings which can be very helpful for you.
Jack: Oh, thank you very much. I will try to follow your advice.
