Friendships in later-life adulthood, which begins in one’s sixties, are often remnants of previous friends and friendship patterns. Those who have typically had a gregarious social life will continue to associate with friends if physically and mentally able, and those who relied primarily on a partner, family, or limited close friends will have more limited, but perhaps equally rewarding, interactions. Friendships that have extended from adulthood or earlier are often “old” or “best” friendships that offer a look into a dyad’s shared past.
