Relativity enhances the best way to see any event occurred, that is, everything will depend on the point of view of where the observer is, or who lives certain experience in any space time of his life, therefore, each person will experience the action of time and the occurrence of an event differently from other people who are even very close to it in motion both, including at rest, and everything will depend on the position of the people involved in the event or simply depend on their criteria forged through his life.
Generally, when we talk about adding and multiplying, these words are related to positive facts, but when we refer to subtracting or dividing, these words could be related to an action or negative aspect in the life of a certain person, and it is not always this way, that is, everything keeps relativity according to the person to whom it is applied or to a fact that we want to analyze, for example, we can express; you must add people with positive attitudes to your side, but we could also express; you must subtract people with negative attitudes to your side.
Although the first expression is very positive because it includes the word add, the second is also positive because it subtracts negative aspects to your life, that is, the words will have a meaning according to our action of relativity in terms of the application of these, therefore, the meaning of relativity comes to offer the balance of the application of each word as well as to respect the diversity of thought among human beings, for example, some actions or activities that make some people happy, not necessarily other people feel the same way.
Many people try to frame other people under their perspective of life and they will always be wrong, hardly voluntarily someone will behave as we wish, possibly our children at some point comply with our standards set at home, however, intrinsically possess their criterion of relativity in proportion to their age, something that over time will be adjusted in relation to their experiences.
Therefore, I think that in our conduct or human behavior and even extrapolated to other living species, nothing is absolute, everything is relative and, this, due to our intrinsic aspect of particularity of thought that we possess until the end of our days of life, of course, my words or expressions are totally relative to the criterion of each of the people who logically live their lives from another approach different from the one I can perceive with each of my senses.
Until another opportunity my dear friends.
