“Psychologists have long described four major types of friendships: 1) The acquaintance, someone you’d chat with on the street or at a local café, who gives you a sense of belonging; 2) the casual friend, a ‘grab lunch’ pal who often serves a specific purpose, such as a tennis or running partner; 3) the close buddy, an intimate, trustworthy comrade you can say anything to; and 4) the lifer, who’s as deep and forever as family.” [Valerie] Frankel’s research found that women should have 3 to 5 lifers, 5 to 12 close friends, 10 to 50 casuals, and 10 to 100 acquaintances.
