Greater, Lesser - Haves, Have Nots - sure. We all have something no one else has,... ourself. It make you important, whether you know it or not. There are things you will understand that I never will. Who's greater then? There are times when the reverse is true. When people work together in love remarkable things can be accomplished. If parents and families work and function correctly it becomes apparent. In bigger groups, you always have the "expert" you need, just when you need one,... "Oh,... I know how to do that!" someone will say, "I just didn't think it was all that important."
Who knows how to work on a car? I do,... but I can't sing to save my life, although I love music. I had to find a way to express myself with a saxaphone. My brother thinks that's wonderful, but I, on the other hand, watch him guide 35 kids to work together and learn (he's a High School teacher). Thirty-five kids would probably train me to sing badly for their parents or something.
We suffer when people are mean to others, because it makes them feel unwanted, they sometimes give-up. Being nice is important, and caring is vital. It's what you have that you give to others that makes you great. What you hoard, what you withold and who you can hurt,... don't make you great.
