 Person2:  Mmm .  
 Person1:      Well , I was walking down Nan Jing Dong Lu ( Nan-Jing E . Rd . ) during my lunch break thinking about this boy-I have no idea why I was thinking about him .  
 Person2:  Really ?  
 Person1:      Yes . And suddenly I heard someone call my name . I turned around and there was this man looking at me . I didn't recognize him at all , but he obviously knew who I was .  
 Person2:  Oh , yeah , that's embarrassing when that happens .  
 Person1:      You got it . Well , he walked up to me and said my name again and then I realized it was the boy I had been thinking about , the one from third grade !
