Behave yourself

I found some annoying girls in one of my lecture this semester.
They don't know what is 'silent'.. Keep chit-chat in the lecture.

If u are good students, no need listen to lecturer teaching, pls don come for the lecture!!
Cant your ppl just sit there and pretend to listen during lecture time?

Besides that, they keep saying bad words about every person who walk into the lecture hall!
FOR WHAT?! Is this your business girl?
Let me felt super uncomfortable!!

你们凭什么批评别人？！
