"Nosy" refers to a person who is overly curious about the private matters of others. This behavior often involves prying into personal conversations or situations that do not concern them. While curiosity can be a natural trait, being nosy typically crosses boundaries and can lead to discomfort for those being observed. People who are nosy may ask intrusive questions or seek out information without permission. This can create tension in relationships, as it may be perceived as a lack of respect for privacy. Understanding the difference between healthy curiosity and nosiness is important for maintaining trust and respect in social interactions.
