Think of 'impassive' as having control over facial reactions in emotional situations.

Facial Control

'Impassive' doesn't mean a person doesn't feel emotions, just that they don't show them.

Not Cold-hearted

Being impassive is often seen as professional, avoiding bias in serious situations.

Professional Settings

'Impassive' implies a distance from emotional involvement, not just outward expressions.

Emotional Distance

In stories, an impassive character might suggest mystery or hidden depth.

Narrative Use

Don't confuse 'impassive' with 'passive'; the former is about emotion, the latter about action.

Avoid Misuse

 You might think of Spock, or it might conjure and image like this -- a cow standing in the rain. It's not sad. It's not particularly happy. It's just an impassive creature taking whatever life sends its way.
