Q: Person1: Good afternoon . What can I do for you today , Madam ?
Person2:It's a little sensitive , actually . I need to get hold of some money , and quickly .
Person1: OK , Madam . We are here to help .
Person2:I already have some Time Deposits with you , but unfortunately , they haven't matured yet . I really don't want to cash those just yet .
Person1: I understand completely . There are other options , such as a Personal Pledge Loan .
Person2:I've not heard of that , could you tell me more , please ?
Person1: The procedure is really simple and convenient . All you need to do is fill in this Loan Application form .
Person2:Right ... anything else ?
Person1: Of course , we'll need some documentation from you . Like your resident permit , proof of salary and your USD Deposit Certificate , to use as collateral .
Person2:And then I just sign here ? You're right ! It certainly is simple and extremely convenient .

Q: Person1: It smells like an ashtray in here !
Person2:Hi honey ! What ' s wrong ? Why do you have that look on your face ?
Person1: What ' s wrong ? I thought we agreed that you were gonna quit smoking .
Person2:No ! I said I was going to cut down which is very different . You can ' t just expect me to go cold turkey overnight !
Person1: Look , there are other ways to quit . You can try the nicotine patch , or nicotine chewing gum . We spend a fortune on cigarettes every month and now laws are cracking down and not allowing smoking in any public place . It ' s not like you can just light up like before .
Person2:I know , I know . I am trying but , I don ' t have the willpower to just quit . I can ' t fight with the urge to reach for my pack of smokes in the morning with coffee or after lunch ! Please understand ?
Person1: Fine ! I want a divorce !

Person2:It's much better now . Thank you .
Person1: You're welcome . And if you need any other things , please let us know .
Person2:Ah , yes , the room is too cold for me . I feel rather cold when I sleep . Can you turn off the air-conditioning ?
Person1: The air-conditioning is already off , madam .
Person2:Maybe I'm getting a cold .
Person1: Would you like an extra blanket ?
Person2:OK . And would you please get me some hot water , too ? I think I need to take some medicine .
Person1: Certainly , madam . I'll be right back . Here is a blanket and hot water for you . Anything else ?
