Tit-for-tat giving refers1 to giving a gift to someone who has bought you a gift. It is not a way to express love; instead, it is more similar to paying back money.
其他人送给你一个礼物,你也买一个礼物送给那个人,这就是以礼还礼。这不是表达爱的一种方法,这种礼物交换更像是还钱。
Example:
We do tit-for-tat giving, and the end result is I buy you one, and you buy me one. We end up giving stuff2 that people will never use.
大家以礼还礼,结果就是我给你买一个,你也给我买一个。最后大家都送了其他人永远都不会用的东西。
