Well some people are better off not saying anything if they can get it back under control themselves. I mean it depends upon the kind of people they have around them. Some see this as an opportunity to see how strong or weak that person is. Which is inconsiderate but to me it is the person's choice to decide whether or not to say something. It might not even help, it may perpetuate it like everything else. Focus on the goal and desired result not the mistake.
