读书感悟

来自《恋恋笔记本》

• 一生至少该有一次，为了某个人而忘了自己，不求有结果，不求同行，不求曾经拥有，甚至不求你爱我。只求在我最美的年华里，遇到你。
  In your life, there will at least one time that you forget yourself for someone, asking for no result, no company, no ownership nor love. Just ask for meeting you in my most beautiful years.

• 爱情没有那么多借口，如果最终没能在一起，只能说明爱的不够。

• 我 没有什么特别的 只是一个 有着普通想法的普通人 过着普通的生活 没有人为我立碑著书 歌功颂德 我的名字也将很快被人遗忘 但是在一件事情上 我比任何人都要成功 我全心全意地爱着一个人 而且对我来说 这就足够了。
