No, of course you haven't. Why not? Is it because nothing positive ever happens? Impossible! Or is it because the media and their advertisers believe that no one wants to hear good news? Possibly, but I doubt it. What about you? Are you satisfied hearing about the latest hurricane, volcanic eruption, flood, forest fire, terrorist attack, mass murder, sex scandal, or other such mayhem? How do these calamities affect you? Do they make you feel good because they happened to someone else and not you? I doubt it.
How about a balance in the news we watch? Would you be in favor of one channel devoted exclusively to positive, uplifting news events? Or perhaps one half hour a day of such presentations on each of several leading stations? Or even one hour a week? Would you tune in? What is the last thing you watch before going to bed at night? Does it help you sleep better? When the news reports a story of the most recent battle or sniper attack in some far away country do you like to see the bodies strewn all over the street?
I believe people deserve something better than what we are getting currently. A choice perhaps, a choice between negative and positive, or an even balance. Take your pick.
