Person1: Daddy , I love this Happy Farmhouse . It's really fun .
Person2: Great . But no talking , now . Don't forget that you are on a ladder . Take care !
Person1: But you are holding it for me . Nothing to worry about . I trust you . Oops , what's that ?
Person2: Don't touch it with your stick . It's a bumble bees ' hive . Get down the ladder . Be quick .
Person1: What would happen if they started attacking you ?
Person2: You can get killed . No kidding . Remember , never stir up a hive .
Person1: I see . Why do people come all the way here to pick apples by themselves and take them home ? Isn't it easier for them to buy the apples in the supermarket ?
Person2: It's for fun . And also , the apples here are Green Food .
Person1: Come on , daddy . You can see that people only pick the red ones .
Person2: Silly boy . Green Food means the plants grown without using any chemicals , fertilizers , and pesticides .
Person1: Oh , then what would happen if there were pests ?
Person2: I heard they used ultraviolet lamp to kill pests .
Person1: Cool ! Well , let's go over there to join mom . I want to tell her all about the special pests-killing method .

Person1: Hey , Leo . How come you look so terrible ? What ' s going ' on ?
Person2: You can say that again . Susan ' brother dropped in from out of town , so I offered to put him up for a few days . But he ' s driving me up a wall . This guy is bottomless pit .
Person1: How gross ! I can ' t handle people like that . Does he at least give you a hand around the house ?
Person2: He doesn ' t lift a finger ! I bend over backwards cleaning up all day and he sleeps in until noon .
Person1: Man , what a freeloader . You better do something quick or he ' ll never hit the road . After all , he ' s got it made in the shade here .
Person2: You think he might stay even longer ? !
Person1: Now , don ' t go losing your temper . If you tolerated all you can , just kick him out ... but do it with gloves . I know ! Tell him a white lie like you ' re getting the house fumigated !
Person2: That wouldn ' t be a lie !

Ex Input:
Person1: Merry Christmas !
Person2: Huh ?
Person1: I said Merry Christmas ! Don't you know that Christmas is almost here ?
Person2: It is ? Oh , that's nice .
Person1: Huh ? Didn't you know ? Aren't you excited ?
Person2: Actually , I'd forgotten about it .
Person1: Forgotten about it ? How could you ?
Person2: Because I'm not Christian , I'm Jewish .
Person1: Oh , I'm sorry . I didn't know .
Person2: It's all right . There are so many Christians in America that everybody takes it for granted that I'm Christian .
Person1: I guess so . So what do you do around this time of year ?
Person2: Well , I'll celebrate Hanukah soon , but that's not as important to us as Christmas is to you . Mainly I'll just enjoy the holiday break .
Person1: Well , would you be horribly offended if I invited you to a Christmas party at my house ?
Person2: Not at all . A party is a party . I'll be happy to come .
