中国語日記翻訳【25】

In other words, my paper diary was originally a “schedule book.” Then I started writing a diary, which turned into a “diary and schedule book,” and eventually just a “diary.” Today, as usual, I will be recording in the 5-year-old journal that I purchased 3 years ago.

换句话说，我的纸质日记本最初其实是一本“行程本”。
后来我开始写日记，它就变成了“日记＋行程本”，最后又变成了单纯的“日记”。
今天也和往常一样，我会继续在那本已经用了 3 年、但买来已有 5 年的日记本里记录。
