Educated：独立成人

"That night I called on her and she didn't answer. She left me. She stayed in the mirror. The decisions I made after that moment were not the ones she would have made.

整整一年前的今天，2019 年 12 月 30 日，我第一次看到新冠的消息。当时离金银潭医院收治第一位感染的病人已经过去了近一个月，已有实验室测序发现是类似 SARS 的新型冠状病毒（注 1）。此时离官方确认人际传播还有 21 天，离武汉封城还有 24 天。
