P.S.: A big Heloise hug to all firefighters (regular and volunteer) across the country. You risk your lives daily for the rest of us.
I want all of your readers to know that closed captioning is required by law on all TVs over 13 inches, and on all digital cable boxes. It may not be as easy to set up as simply pressing the mute button, but it may come in handy for some people. Refer to the instruction manuals. Also, you can leave the sound up while the captions are going.
