Input:  Person1:       Right , that ends the third and final part of our presentation . I'd like to end by emphasizing the main points . I'll give you a brief summary . There are three potential areas for development in the future , domestic , overseas market , and the internet . Each of these markets have their own particular need for marketing strategy ... for domestic , we can rely on past research , for overseas markets we depend heavily on our cultural consultants , and for the internet , we need to redo our image to appeal to a young set of consumers . Our main issue here is that we need to be sensitive to the needs of different markets in order to continue to see success . Mark , did you have anything to add ?  
 Person2:Yes , I want to restate one more time the importance of reinventing our company's image to appeal to different customer bases . I want to end with a true story that has to do exactly with what we've been talking about today ...
