上高中了，是我这辈子遗憾最多的日子。起先，在那所我极不愿去的学校里，我没有记住爸爸的话，看着身边的老师、同学，都找不着感觉，并且越来越讨厌那种环境，后来干脆开始逃课。逃课的日子多了，就成了老师眼中的坏孩子，其实在那所学校里逃课的学生多的是，但是老师好象长了一双只可以看到我逃课的眼睛。后来，老师要我来写保证书，保证我以后不再逃课，否则就走人。我写了，并且在班上念了。因为从心里我是真的想读书，可是每次总是管不住自己，有一种想逃走的感觉。现在想来，我那时应该是或多或少有些郁忧症了。所以保证书过后，我又逃课时，老师叫来了我的爸爸，并且要求爸爸写保证书，保证我以后不再逃课，而且要当着班上的同学念。我马上拒绝了，只说了句：&我自己走吧。&
