Boundaries are limits that individuals set to protect their personal space, feelings, and well-being. They can be physical, emotional, or social, helping to define what is acceptable behavior from others. Establishing boundaries allows people to communicate their needs and preferences clearly, fostering healthier relationships. In various contexts, such as friendships, workplaces, and families, boundaries help maintain respect and understanding. For example, someone might set a boundary by saying they need time alone after a long day. This clarity helps others know how to interact with them, promoting a more positive and supportive environment.
