Aggravated feeling of justice
There are people who have a greater sense of justice than others. These guys and girls always try to live according to their conscience. Yes, this desire is not developed by parents and upbringing, but there is a delay. It is very difficult for such a person to act dishonestly. Up to a certain point, he does not understand how one can be dishonest with someone. That is why such people are very open and trustful. They judge all the people. A hypersensitive person will never discuss someone, dissolve gossip, blame something without evidence. He does not tell the secret of secrets and does not betray those who trust him. That is why it is very difficult for such a person to understand and accept the fact that almost everyone can something to talk about, it's ugly to act with a friend and acquaintances, and so on. Along with justice, there is always credulity. Therefore, quite a long time, these people are still open to others, try not to hide anything especially so further. But then a moment comes when they understand: they are treated unfairly. And from this awareness it becomes very painful, because justice is what, in fact, is what keeps the life of such a person. If there is no justice, then life will lose its original meaning. It is disappointment that causes a person to become isolated in himself and cease to trust other people. He simply does not want to be treated unfairly again. He begins to realize that all people are far from ideal. It is worth noting that very often people cease to talk about themselves and because they simply do not want to lose those whom they still consider close. Old friends and friends of such people are very surprised and often say that a person used to be so and was not clear what happened to him now. Unfortunately, most of them do not even understand that it was their own behavior that, to a greater or lesser extent, caused such dramatic changes in the character and behavior of a person. Perhaps, the unfair treatment of people, disrespect for their personal interests in their personal lives, is the main reason why a person closes up and ceases to trust people. Although, there are other cases.
Look for a woman ... or a man
The reason that a person has become cold and closed, can become unhappy love. For example, a guy loved a girl, long sought, but she was always a little, she was constantly unhappy with him. Vitoge, he realized that it is better to abandon your feelings altogether or even to hide them, than to constantly fight, like a fish about ice, without any results of its activity. Otherwise, a person can simply learn about the person who is in love and this will also affect his behavior, openness and sociability. In love we need trust. If we do not find it or lose it, then a serious disappointment comes. We all know that starting to love someone, a person creates a vegan image, exaggerates the good qualities of a loved one and so on. If love is reciprocal, and the object of attention is a good person, then such an idealization does not harm. But when we fall in love with the wrong thing, in the end, such an image will crack at the seams, and then completely scatter into a thousand small pieces, wounding the namdushu. Many men and women become wary, cold and silent just after a hard and painful break. They stop contributing and trusting people for two reasons: either they do not want to not open themselves to anyone again, so that they do not experience the pain of love and loss again, or not at least open up, because now they are sure that close people are always capable of predestination, and this is too difficult to survive. Therefore, disappointment and parting can cause such a serious injury that a person closes in himself or ceases to trust someone in principle. Of course, in this case a new love can save a person. But it's far from the fact that he will really let her to her. There are those who are disappointed once perezhivyvayut so much pain that in the end they update their heart-tested fence and do not let anyone in if not all their lives, then a very long time.
In any case, if a person suddenly became confused and distrustful, it means that in his life there was some very serious event that made people reconsider their attitude towards people in general and in particular. Never in a lifetime do people change at one time for no reason.
