Someone does something to offend you. You get angry. The other person gets angry back (or perhaps feels appropriately guilty). Emotions often unfold like this as a consequence of somebody else’s actions or emotions. And they rarely simply ﬁzzle out without having any further impact on the interpersonal world. Indeed, it is usually hard to ignore other people’s emotions. Just as an outstretched ﬁnger tends to direct attention wherever it points, a witnessed emotion encourages us to take account of its implied perspective on events.
