After a long day, Snape has just returned to the dungeons when he sees a message from Dumbledore. The sky he had just patched up collapses once again...
Dumbledore: Exhausted, exhausted, exhausted, exhausted...ing
Ling Yufeng: You wouldn’t be so exhausted if I gave you a Grindelwald.
Snape: Mocking, mocking, mocking...ing
Ling Yufeng: Professor, your insults aren’t remotely classy or impressive.
Voldemort: Avada Kedavra!
Ling Yufeng: If you’re bad, practice more. If you can’t handle losing, don’t play.
Harry: Teaching assistant, how do I do this?
Ling Yufeng: Do I look like a walking encyclopedia to you?
