It has been Decided!

Yet another reason to avoid the passive voice. But note: Quinn's final two examples of the passive voice are, in fact, past tense yet active verbs.

Both "mistakes were made" and the more informative "mistakes were made by the Decider," are passive. However, and contrary to Quinn, sentences of the form "the Mistaker decided" (and, obviously, "the Decider made mistakes") are not.
