Definition: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues.

Input:  Person1:       So , Fred , what are your plans for after graduation ? 
 Person2:Well , I ’ Ve already got a job waiting for me back in my hometown . 
 Person1:        That ’ s cool . Have you already found an apartment to live in ? 
 Person2:I ’ m planning on living with my parents . Won ’ t you ? 
 Person1:        I couldn ’ t even if I wanted to . My parents told me that if I went home , then ’ d have to find my own place . 
 Person2:You mean they ’ re kicking you out ? 
 Person1:        Not really , they just don ’ t want me living at home . My older sister did that , and she lived at home for seven years . Once she started living at home , it got harder and harder for her to move out . 
 Person2:Well , it ’ s not like my parents want me to live at home the rest of my life . They said that it ’ s ok if I move back home to begin with , but they want me to find a place of my own after a year or so . 
 Person1:        My parents just didn ’ t handle my older sister very well , and because of that , they want me to be more independent . They think that it ’ s important that I should learn how to live on my own . 
 Person2:I know I need to learn that myself , but I just don ’ t have the money for it at the moment . Living at home allows me to save up some money before I started finding a place .
