This short article is essentially a continuation of my first article on the formation of boundaries in children and is inspired by my thoughts about defending our personal boundaries... We all, one way or another, face the problem that it turns out we don’t know how to defend our boundaries and allow others to violate our boundaries. As for me, I can say that for so long I was known as a trouble-free person and was afraid to say the word “no” even to the detriment of my interests. And only after taking a course in psychology, personal and group therapy, I I can say with confidence that the roots of our inability to defend our boundaries go back to childhood - as children we want to be obedient and good girls, hoping to earn the love and praise of our parents, and so this habit accompanies us throughout life. As for the current situation, I have learned refuse requests and at the same time listen to yourself, check with yourself, your desires, capabilities, try not to follow other people’s manipulations and not feel guilty. And also respect and try not to violate other people’s boundaries. I’ll be honest, to learn this, you need a decisive attitude , the desire to change something, check with your desires, analyze the situation and have a certain courage. Children use the word “no” more actively in their vocabulary and one can say that at certain age periods of childhood it becomes a favorite among children, since the word “no” accompanies children’s negativism in crisis moments of a child’s development. It is surprising that with age it is either somewhere in the “backyards” of the lexical dictionary, or is used in minor everyday situations. Why, as adults, we cannot say a decisive “no” to unwanted manipulations from the people around us and defend our boundaries? I think we are afraid of: a). offending someone with our refusal; b). we are confident that our reliability gives us the right to expect the same reliability from others; c). we are afraid of condemnation from others and being branded an egoist i.e. fear of being branded a “bad” girl or boy; d). In some cases, this is facilitated by the authoritarian style of parenting (“I said that’s all”); e). Until recently, the social system and our education system cultivated trouble-free behavior ( Soviet ideology, enthusiasm, public condemnation of selfishness, etc.), and our generation comes from the USSR.
