Q: Person1: My computer isn ' t running at the same speed it used to be , it is testing my patience everyday . Can you tell me how to make it run faster ?
Person2:If you want to speed up your system , you ' Ve got to clean it up first .
Person1: How ?
Person2:You need to free your disk space . The simplest way is to use a Disk-Cleanup tool to remove temporary files and in store programs that you no longer use . Things should be fine next time you start . You also need to control what starts up . There is a program calls Start-up Delayer , It can help to set after how much time programs should be loaded after Windows boosts . For example , you can choose to set your Fox Mail program to load 30 seconds after Windows starts up .
Person1: Very useful advice , I will try them right now .

Q: Person1: Hello , Dana Okro .
Person2:Hello , Dana , this is Kevin Abrahams from Eureka Corp . I don't know if you'll remember me but we met last week at the Chamber of Commerce luncheon .
Person1: Oh , yes . Hi , how are you ?
Person2:Great . Do you have a few minutes right now for me to tell you a little bit more about the data management tools our company has to offer ? It won't take long .
Person1: Actually , I'm really swamped right now and I'll be going into a meeting in a few minutes . Is there any literature you can send me ?
Person2:Oh , sure , I understand . I'd be happy to send you a promotional packet about the programs that I think might best suit a company of your size . Would it be okay if I called again to see if you have any questions ?
Person1: Let's do this . Since I'm not sure when I'll get a chance to read the material , why don't I give you a call if I have any questions . Now , I'm really sorry , but I have to get going to this meeting .
Person2:No problem at all . I won't keep you any longer . I'll put a package to you in the mail and we'll go from there .
Person1: Sounds good .
Person2:Thanks for your time .
Person1: No problem . Bye , bye .
