Social circles refer to the groups of people with whom an individual interacts regularly. These groups can include friends, family, colleagues, and acquaintances. Social circles often share common interests, values, or experiences, which help to strengthen their connections and foster a sense of belonging. The size and composition of social circles can vary widely. Some people may have a large circle that includes many acquaintances, while others may prefer a smaller, more intimate group of close friends. Social circles can also change over time due to life events, such as moving to a new city or starting a new job, which can lead to the formation of new relationships.
