We live in a modern age in which there are those who believe that virtual reality, robots, and artificial intelligence will somehow not only make the world a better place but will also serve as a worthy substitute for alternative human interaction when traditional human interaction is unavailable or unobtainable for certain people under certain specific circumstances. It is, though, hard to actually believe that human beings as social creatures can ever find true satisfaction in artificial constructs, as thereby serving them well regarding their happiness and self-esteem, because this would seem to fundamentally misunderstand what humans really are, and what they actually require to live a good and wholesome life.
The truth of the matter is that those that are not ever touched by a caring hand and thereby are essentially ignored, are the very same that are not in a good place and are thereby going to suffer from the feelings of neglect, and the feeling that nobody cares about them because that very lack of the human touch, distances them from the society that they should be an integral part of. While not everybody wants to be hugged or touched all of the time, most people, not only appreciate a good hug but definitely desire to have those hugs, especially when they are most in need of the human touch and care.
We as humans are social beings, which thereby necessitates us to communicate and to be in harmony with one another, and while conversations with other humans most definitely have their place, it has to be recognized, also, that most human beings also yearn to touch and to be touched by the other, because it typically brings them contentment and joy. Those then that dismiss this as not being necessary for blissfulness are either not in a good place to begin with, which thereby means that they definitely need to feel some human caring, or are too caught up in worldly things or their own intellectuality to comprehend that their physical and emotional self needs care, as well.
So too, those that are most violent or filled with hatred are not going to be those that have experienced an abundance of love and care in their lives, but rather are typically going to be those that are upset about perceived wrongs done against them as well as the perception that nobody cares about them, thereby making it easier for them to strike back at someone or something because they lack the feeling that they are appreciated by their fellow humankind.
We are no more and no less than what we perceive ourselves to be, and when that perception tells us that we need more of the human touch, but we are unable to experience such, our overall life experience is not going to put us in a desirable place. To be cared for necessitates not only a helping hand but also an unjudgmental ear, in addition to receiving the touching by the other that is freely given to us, and those who experience those very things are going to not only feel better and more appreciated, but will typically reciprocate in kind.
