For Example:

Sam, who works at the information desk, has heard through the grapevine that there is a celebrity currently undergoing cancer treatment here at the hospital. A member of the news media approaches him for information about this person's condition and treatment. When Sam looks at the patient list, he sees that this person has "opted out" and is not listed. Sam tells the reporter, "Yes, that person is here and is currently undergoing treatment for cancer but that's all I can tell you."

Did Sam say too much?
