Are you OK ?  I'm fine . I'm just so touched by the sad story .  So I can say now that you must have enjoyed the opera . Which scene is your favorite ?  I love them all . But if I had to name one as the best , I would say it's the ending .  What's it about ? You know , I couldn't help falling asleep .  Did you ? I didn't notice that . But still you should know it , for you have seen it with Laura before .  I guess I've done the same thing last time I was here with her , too . I mean falling asleep . For me , this one is not that attractive .  Then I doubt if you like operas at all .  Yes . I like Carmen very much . But I don't mind if you want to tell me about this one .  OK , then . The man was old and he was visiting his wife's grave , with a rose in his hand . When he got there , he saw someone already put a rose on her grave .  Very impressive . And I do like the leading actress who has an amazing voice .  Me , too . There was always a good round of applause every time she sings .  Yes , the applause ! That was what kept waking me up during the show .  And it's been such a faultless performance with the perfect lighting , and music . Just amazing !  No doubt , it's not a simple thing to put on a ' phantom show ' .  Exactly . 
Yes
