机械系的好像在5楼还是6楼我忘了，跟楼梯是斜对面！

机械系 坐电梯上五楼 一出来就是

When tomorrow turns in today, yesterday, and someday that no more important in your memory, we suddenly realize that we r pushed forward by time. This is not a train in still in which you may feel forward when another train goes by. It is the truth that we've all grown up. And we become different.
当明天变成了今天成为了昨天，最后成为记忆里不再重要的某一天，我们突然发现自己在不知不觉中已被时间推着向前走，这不是静止火车里，与相邻列车交错时，仿佛自己在前进的错觉，而是我们真实的在成长，在这件事里成了另一个自己。
