Is There a Detoxification Hypothesis of Tears?

In the next episode, i think we're gong to get more into the direct formulations of some of the main contending hypotheses or for explaining the biological evolution of tears. But want to talk about some some broad observations in the idea of tears as an external or inter personal adaptation that serves a relational function. And one piece of evidence that seemed somewhat convincing to me is that people just automatically, when they observe tears, interpret them as convey in information about the emotional states of the person who's crying. The tears themselves seem to convey very important information.
