Mary , be calm .   It is impossible . You cheated on me .   No , listen to me . I always regard you as my best friend . I admire you , and of course you've helped me so much . I should thank you .   Shut up !   No , listen to me . Perhaps it's my fault that I treat everybody so well . Maybe in other people's eyes , I want you to be my girl-friend . but ... but ...   But you have had lily already ? You should have told me about her , but you didn't .
