And we know that you can be lonely in a crowd and you can be lonely in a marriage, so the second big lesson that we learned is that it's not just the number of friends you have, and it's not whether or not you're in a committed relationship, but it's the quality of your close relationships that matters.
而且即便你身在人群中， 甚至已经结婚了， 你还是可能感到孤独， 因此我们得到的第二大结论是 不是你有多少朋友， 也不是你身边有没有伴侣， 真正有影响的是这些关系的质量。
