6. (1) Primary relationships—with our relatives, friends, or neighbors—are very precious to us. (2) As research has shown, they are particularly helpful when we are going through stressful life events. (3) They help ease recovery from heart attacks, prevent childbirth complications, make child rearing easier, lighten the burden of household finances, and cushion the impact of job loss by providing financial assistance and employment information. (4) However, secondary relationships have their own special benefits. (5) Our close friends may not help us, for instance, get as good a job as our acquaintances can. (6) Our friends move in the same social circle as we do, but our acquaintances, to whom we have only weak ties, move in different circles. (7) As a result, we may already be aware of the job openings known to our friends, but we may not know of the many other job opportunities our acquaintances can tell us about.
