the degree of solitude necessary for a person to feel psychologically comfortable and safe. It differs depending on:
1) Personality traits: An introverted person may want more isolation than a sociable person.
2) Situations or environments: work, home, public places.
3) Culture and social values: In some cultures, there is a greater distance between people.
The incompatibility of available and desired privacy can lead to stress, frustration, or defensive behavior.
