[Q]: Person1: Good day ! What can we do for you ?
Person2:I'm considering buying a new car , the old one hasn't been running too well recently , and was wondering what kind of credit you can offer me .
Person1: Buying a new car is a big expense ; we understand that , so we have a variety of loans to suit your needs .
Person2:That's great . I'm looking to borrow quite a large sum , though .
Person1: With our Personal Automobile Consumer Loan , the borrower can borrow up to 80 % of the purchase price .
Person2:That's good news . The car I'm interested in is priced at 120,000 RIB , but I think I can get a bit of discount on that . I can afford to put up around 40,000 RIB myself .
Person1: That's great . You will need to make an initial down payment of 20 % , and then we can get going with this .
Person2:The funds are all ready to go in my personal account , so let's transfer it .

Person2:Yeah , but sometimes Bingo wants to play with me , but I don't have time .
Person1: So who takes care of him then ?
Person2:My little brother likes to play with him . He even gives him a bath every week .
Person1: I can't do that with my cat . She hates water .
Person2:You know , you're right . Maybe you should get a dog .
