When I came back to the small room without any sound, suddenly I did not want to do anything. It might because the switch from the group of people to one person, I still cannot adapt to the lonely night. During the way back to Oxford, I sat next to S, seeing the ground far away when he was driving. I asked him if he had a nice sleep yesterday, he told me he woke up three times, I was curious about the reasons. I was surprised that he told me it was the message from his girlfriend in China that woke him up. He is sensitive to the phone shaking from her girlfriend. Frankly speaking, I am jealous about his love towards her girlfriend. I don't think I deserve someone to treat me in this way, namely, I dare not expect there will be such a person in my life.
