Hypothetical situation.

Let's say you were reading samples of some letters that recently went out to alumni of the school you work at. And let's say that on one letter, there is a very small mistake, one where one measley little word is left out.

Would you, knowing that this particular letter bearing the mistake has already been mailed, mark the mistake in HUGE letters, where everyone else in the office can see it, then present your discovery to both the Associate Director and the Director somewhat proudly?

Or, would you discreetly bring the mistake to the Director's attention and commiserate on the fact that yeah, sometimes it happens?
