If they don’t tell us why then we don’t learn anything.

[null and void]

Worth repeating:

If they don’t tell us why then we don’t learn anything.

May I add:

Since we don't learn anything we keep making the same mistakes and the Mod Squad has to painstakingly punish us again and again and again and again and again.

Conclusions?

The Mod Squad likes creating unnecessary work for themselves. -or- They enjoy punishing us.
