Do you know what is T4 ? Let me explaint it for you. It's about a group of four people who like to share his or her expereance with each other. We have a shortlived conversation after class when we have courses in school.
Even the janitor of Wenzao college can recognize us because we are persons who often leave school later. Almost four years, we still gather at parking lot to enjoy the period of talking. Therefore, we named ourselves a title "Talkative Four".
