Your Sim will sometimes mirror the emotion and detect the body language of other Sims around them.
In CAS give your Sim the Perceptive trait. Located in the Social category.
They’ll perceive the emotion of other Sims and mirror that emotion in most cases with a buff.
There are 10 buffs.
Note: I can’t get rid of the rock group small text. I removed the buff text and it still shows up.
