Have you ever wished 'they' would just be quiet? It's amazing how little can be said in fifteen minutes. You can get the feeling that something else--maybe a lot else--is going on, the longer it takes to "answer" the question and the less seems to be said. More words can be more information--or not.
As a citizen, I've had my comments limited to the proverbial 3 minutes. I've also wished that officials would limit their own comments. As a candidate, my speech is still limited during debates, interviews and in my literature. It's good pratice.
As a citizen working on becoming an official, I'm thinking about effective speech and courtesy. Official silence can be a good time to listen.
