I understand why you would say that, but as someone who has been to a classical concert, sometimes the music is so relaxing that it just puts you to sleep ╥﹏╥ I went to go see the Nutcracker and it is personally one of my favourite shows to see, but I still fall asleep during points because the music is so relaxing. Now I’m not speaking for everybody but this could be the case here.
That is true, I agree , I love falling asleep on classical music, however, can you actually fall asleep on a one in a life time date with the person you love? I wouldn't, no matter where and how we are and no matter, how long I haven't slept.
If she was so happy to be on this date, she wouldn't fall asleep on the concert.
