Input:  Person1:     Hi , Michael , how's it going ? 
 Person2:  Well , things are all right . 
 Person1:      I heard you got a new roommate . What's he like ? 
 Person2:  Yeah , Bob moved in last week . He is a nice guy and so far everything is cool except this girlfriend . 
 Person1:      Oh ? What's wrong with his girlfriend ? 
 Person2:  She came over last weekend . She is a nice girl but there's something about her voice that really creeps me out . I tried to smile and be polite , but the whole time all I could think was " what's wrong with your voice ? " 
 Person1:      Well , I guess it might take some time to get used to . 
 Person2:  I doubt it . Last time was an oral train wreck . Listening to her talk is like chewing tin foil . 
 Person1:      Oh come on , it's not that bad . 
 Person2:  No , it's so much worse . And tonight they invited me out to dinner . I really have no idea how I'm going to pull it off . 
 Person1:      Rough . Maybe you can do the most of the talking . 
 Person2:  That's the plan . 
 Person1:      Good luck .
