Person1: yes , she said they couldn't communicate well with each other and they often argued over trivial things .
Person2: yeah . Mixed marriage is tempting but crisis-ridden .
Person1: you said it . You know , they fall in love at first sight and quickly jumped into marriage .
Person2: maybe they were just attracted to each other but too different to be married .
Person1: yeah . We Chinese have quite different lifestyles and values from foreigners .

Ex Input:
Person1: Wow , is that your sports car ?
Person2: Yes , do you like it ?
Person1: I love it ! I used to always want to drive a green jaguar . Is it in good condition ?
Person2: Yt looks good on the outside , but the inside is a different story . It needs a lot of servicing before it can go out on the roads again .
Person1: What's wrong with it ?
Person2: Well , first of all , it needs a new engine , which is extremely expensive .
Person1: When's the last time you had it serviced ?
Person2: It must have been a few years ago now .
Person1: I thought all cars needed regular servicing on a yearly basis .
Person2: They do . Once my son was born , there was no reason to drive this car anymore . It's only a two-seater , you know !
Person1: What else is wrong with it ?
Person2: The heating controls don't work anymore , so it always feels like it's about 100 degrees in the car even in the summer !
Person1: Anything else ?
Person2: The brakes don't really work that well anymore either .
Person1: Why don't you get it all fixed ?
Person2: It costs more than you think to run a car---especially when there are so many things wrong with it !
Person1: Well , let me know when you can get it fixed . I ' d love to go for a ride in it !
