[EX Q]: Yes ! I finally lost that last five pounds I've been working on forever ! How did you finally do it ? A friend suggested that I stop nibbling between meals . Like snacking ? You know , a little piece of chocolate here , some chips on the side , candy now and then ... I get what you mean . Instead , I sit down and have a good snack like a piece of fruit between meals . I'm impressed . Good for you !
[EX A]: Yes

[EX Q]: How much is this shirt ? 80 yuan . It's rather expensive , isn't it ? It's a bit . But I can give you a discount . How about 50 yuan ? No . I'm afraid the price is too low . Then let's split the difference and I'll give you 60 yuan , OK ? I'm sorry , but I think you should give me no less than 65 yuan . All right .
[EX A]: No

[EX Q]: You ran the stop sign . May I see your driver's licence , please ? Oh , I'm sorry . I didn't see the stop sign at the corner . I didn't mean it . That doesn't justify your violation . May I see your licence , please ? Oh , sorry , I don't have it on me . Honestly , I forgot it at the house . But I have the insurance policy with me . Here it is . Well , sir , your insurance looks good , but I still have to write you a ticket . I understand , officer . I guess it's just not my day today . I will accept the fine .
