Q: Person1: So how's everything going for Christmas ?
Person2:I've got all the presents I need , and my family is working together to get all the food ready . That's easy , but I have another problem to deal with .
Person1: What's that ? Don't tell me you've still got Christmas cards to write , it usually takes my wife a month to write all of ours .
Person2:No , I did that a long time ago . It's about telling my son the truth about Santa Claus .
Person1: He still doesn't know that Santa isn't real ? How old is he , eight ?
Person2:Yes . He's never said anything so I never told him . But now that he's getting older ...
Person1: You think it's better that he should be told ?
Person2:Yes , he's too old to believe in that type of things . And I'd rather tell him before the kids at school do .
Person1: That happened to my oldest girl . She became really upset when her classmates told her Santa wasn't real .
Person2:I can understand . I was lucky with my oldest , she figured it out by herself and didn't tell my son .
Person1: Well , when you tell him , be gentle . It's hard for kids to find out something like that .

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 .
