Person1: I ' d love to have my own farm .
Person2:It would be very hard work . Are you sure ?
Person1: I wouldn ' t mind getting up early morning and the physical work would make me fit and healthy .

Person1: That ' s one reason I ' d like to try it . I ' d really like to get away from working 9 to 5 in an office .

Person1: Welcome ! Welcome to Little Italy . We're the most Italian family here !
Person2:So I've heard . That's why I'm having such a great time .
Person1: If I hadn't married an Italian man , I probably wouldn't be pregnant so often . And maybe I could raise pigs instead of bambinos !
Person2:Huh ? Um ... well , it's nice to see that some people still have big families .
Person1: It is nice , but it would be nicer if my macho husband would get off his tush and help me . Ha-ha ... Have this . It's from Italy !
