 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 .
