Definitions, an incomplete thought and theory

It's funny but my butterfly post yesterday and even my million tiny pieces this morning got me thinking about definitions. How the way we define a word, a feeling and even an emotion can vary so enormously from person to person.
How what I see as beauty is very different from what any one of you would see as beauty. How if you had to show a group of 10 people the exact same picture, each of them would react differently to it, yes they may all see it as beautiful but if you asked them all why, the answers you got would all be different.
The same goes for a situation and how those same people would handle it. Each of them would react to it in a way that upbringing, previous experiences and personal growth dictated. So what is breaking down everything I've fought so hard to build may very well be nothing more that a bump in the road to you, but may completely destroy the next person.
Of course this theory of mine comes into its own when we start wondering into the potholed road that is emotions. How you define love, trust, caring and the rest of these emotions that we are all so intent on will be totally different to how I do. The basic premise and dictionary definition may be the same but how each of us experiences them from a personal point of view will be as diverse as all the fish in the ocean.
