Last day of 1st Semester

When i was on the way to school, i expected the train to be crowded. However, it turned out to be empty. why? It is the last day of semester before the three weeks holiday has started! I turned up in class early and 9 of my classmates were here. Today we need not have to present, just share what we have researched during the 3rd meeting and we can go. wee~
