Input:  Person1:       Hello , Sir , may I help you ?  
 Person2:Yes . I would like some information for requesting a loan .  
 Person1:        Very well , here are the general terms of our loan policies . We pride ourselves in having the lowest interest rate in the country for personal loans .  
 Person2:I see . So let me get this straight . If I borrow let ’ s say , ten thousand dollars , how much will I have to pay each month ?  
 Person1:        It depends on how long you take to pay it back . If we lend you ten thousand dollars at an annual interest rate of ten percent for forty eight months , you would have to pay each month a portion of the loan which is called the principal and another small portion of the annual interest rate . This of course is considering that you don ’ t default on a payment !  
 Person2:It sounds good but , there is just one problem . I have a terrible credit score .  
 Person1:        That is a very serious problem you see , the bank must assess your personal information , past loans , assets and any other relevant information such as your credit score in order to approve your loan .  
 Person2:You know what ? I don ’ t really need the money . Thanks anyways !
