So now I'm sitting in this 4-hour ceramah.
And it is organized by those higher-ups management of my university.

Yes. These people who can turn a simple talk into a torture.
What would they feel if they had to sit in a 4-hour ceramah, that's hardly fun nor interactive?

I bet they wouldn't like it either.

So if they don't like it,
Why are they forcing the same thing they'd hate- on us?
