The importance of a two-letter word

As a child, I heard people say that the biggest word in the dictionary was "if". If I were a millionare how different would my life be? If is a pretty big word. What about the word "no". This was always a word that carried it's weight. No is a defiant word which I never allowed my kids to use, or, if they answered me back using that word, they knew it meant --in modern terms, a "time-out". Parents are always the boss, at least they should be. That's how I raised my children, and that is how I was raised. Today I'm thinking that my little grandson loves to use the word "no" because he is aware of what it means. Learning to say "No" is a good thing, that perhaps, I can learn from my grandson. He has a little mind of his own. And, he is not afraid to express himself. If only I could say "no" to many of the sweet things that I know I'm not supposed to have, wouldn't I'd be better off? Today, I think the most important word in the dictionary, if people still utilize one, would be "NO." Should the word "NO" be supressed? Was Dr. Spark right after all? I wonder. How can I correct my little grandson from saying "NO" when I have to learn to say NO, myself? Maybe, "No" is not the biggest word in the dictionary, but it certainly carries it's weight.
