理了理本来就整齐的头发
                                  登上了本来就熟悉的讲台  
                                  讲出了本来就熟练的话：
                                           上课
                                  台下有熟悉学生
                                  也有不熟悉的老师和专家
                                  他们的目光像箭一样
                                  射得我
                                  天旋地转
                                  心乱如麻
                                   漫长，漫长
                                    漫长的寂静
                                    漫长的喧哗
                                         突然
                                     一声悦耳的铃响
                                             下课
                                        哦，哦
                                   是谁的手机
                                   漏铃响了一下？！
