Definition
Undemonstrative describes someone who doesn't readily express their emotions openly. It's like being a closed book—feelings are present, but not easily visible. Undemonstrative people tend to keep their thoughts and emotions private, often appearing calm and reserved. This isn't necessarily a bad thing; it just means they process feelings internally rather than through outward displays. Think of it as the opposite of wearing your heart on your sleeve. A stoic character in a movie who remains composed even in crisis might be considered undemonstrative.
