 Person1:      You must be joking . You can't fall in love with someone you've never met ! 
 Person2:  I know , but I keep thinking of him every day . And I get really depressed when he's not online . 
 Person1:      I think it's just a crush . You can't be serious . 
 Person2:  Well , this might be silly . But I just can't get him off my mind . And I can't help missing him . 
 Person1:      Did you tell him ? 
 Person2:  Yes . He said I'm his dream girl . 
 Person1:      You shouldn't take it too seriously . It might be a lie . 
 Person2:  I know . I can't tell whether he's serious or not so I need your advice . 
 Person1:      I think you should enlarge your circle of real life friends , and then the right person will come along .
