Personal space refers to the physical distance individuals prefer to maintain between themselves and others. This space varies based on cultural norms, social situations, and personal comfort levels. For example, people may feel comfortable standing closer to friends than to strangers. The concept of personal space is important for social interactions, as invading someone's personal space can lead to discomfort or anxiety. Understanding and respecting personal space helps foster positive relationships and effective communication. Factors such as cultural background, context, and individual preferences all play a role in determining how much personal space is needed.
