Instead of building personal boundaries, we were taught to endure, be comfortable, obedient and accommodating. The upbringing system was largely based on guilt, shame and manipulation. We grew up in a society where this is customary, and now, by inertia, we keep our faces, let others ride on our necks, pretend to be a benevolent Mother Teresa helping everyone, and a deadly hurricane of discontent and indignation is raging inside. As a result, all this leads to disastrous consequences: illnesses, emotional disorders and a sense of the meaninglessness of life.
The easiest and most environmentally friendly way is to voice them. Directly and without hesitation. People around you are not telepaths and can only guess how comfortable you are and how not. For someone, it is in the order of things to hug tightly when meeting, and someone restrainedly greets even close friends. Someone calmly gathers large companies at home, and for someone even one guest is a big stress. We are different. But it is not at all necessary that our differences will become an obstacle to communication if we indicate in time where our boundaries begin and end.
