In the morning, my roommate sent a circle of friends after I left, saying, really, I am a light sleeper, don't disturb my sleep! Okay？ I don't know if he is in.

She has a problem with you! But the surface doesn't show it! I don't want you to see it when I say it out!

Maybe you really didn't bother her, but she deliberately gave others the impression that you were bothering her! So I blocked you.

Anyway, your roommate is a terrible person! Because she can communicate with you directly, even if she jokes that you sleep noisily. But she chose to advertise to let others know that she just blocked you. This behavior is terrible!
