Well...for one thing, it's just something you do. Like, we don't choose whether to go or not. And there are a lot more people, so there are lots of classes and it's totally normal not to know everyone.

In my case, specifically, well...I went to a private school. Once I started going to school here, it took me a while to get used to not wearing a uniform and being in class with guys again. Plus the scheduling and stuff. Four days a week? I mean, it's just one day less but, it felt sort of...weird, you know?
