-            <p>好久不见！最近过得怎么样？</p>
-            <p>感觉太敷衍也不太好，但又感觉没什么可写的。今天是2026年6月21日，距离高中毕业已经2年有余，不知道你还活着吗，活得怎么样。其实到这里就已经写不下去，就像那个信封里的一样，我记得好像只写了两行。如果你还没有看那就别看了，上次你还让我用AI写，那是付费内容，ChatGPT一个月$20呢。其实只是感觉用AI不好。平时一直在用AI做各种各样事，感觉再用AI写这个有点不好。</p>
-            <p>（又水了几行）</p>
-            <p>希望你最近能过得好吧。最近我才刚刚结束了为期一个月的期末大预习，甚至有一周考四科外加实习的地狱时刻。其实还有考试要延续到七月中旬，七月底才要放假。不知道你最近如何？</p>
-            <p>好，就这样了，剩下的你自行想象吧！</p>
