And I've talked to researchers and they have very much admitted this, and I think part of it is: it is harder to study when it's not a kind of clear dyadic relationship in the way that you would with a spouse.

我人员谈过，他们非常承认，我认为部分原因是：当友谊不像你配偶那样是种明确的二元关系，起来会更困难。

Apology is a dyadic experience, but forgiveness is freedom.

道歉是种双人体验，但原谅是自由。

But I think you also said somewhere that it's not just that thinking is a group activity or at least a dyadic activity, but it's also work.

但我想你在某处也提到过， 不仅仅是思考是种群体活动， 至少是双人活动，而且它还是种工作。
