Somebody is sad. They could be dealing with something serious like the death of a loved one, but it happens just as often that it's simply a bad day. And how do we know that person is sad if they're not crying or outright saying so? Simple — have them talk less, if at all.
This character is not Dumb Struck— they can speak perfectly fine. They just don't feel like it as much as they would if they were happy. This can range from absolute silence to simply fewer or shorter sentences. Somebody who speaks in Sesquipedalian Loquaciousness might also use shorter words than usual.
Expect everyone to notice (especially if the person is usually talkative since OOC Is Serious Business) and ask what's wrong. The person being quiet may open up, or they might just nod and walk away. There'll probably be a pep talk eventually, whatever the circumstances.
Compare Too Unhappy to Be Hungry and Too Upset to Create for other tropes about characters not doing things because they're sad. Also compare It's Quiet Too Quiet, for when you can tell things are serious because the surroundings are quiet, Stunned Silence for when someone doesn't speak because they're shocked instead of sad, Moment of Silence for the death-specific, cinematic equivalent, Emotionally Tongue-Tied for more positive emotions like love, and Silent Treatment for when someone is angry at another person and so refuses to talk to them.
May be a dark reason behind The Quiet One, The Voiceless, The Speechless, the Elective Mute, or the Silent Bob. See Lost Voice Plot for when someone is outright unable to speak (generally not due to sadness) and it makes up an entire plot.
- Digimon Tamers: Following the death of Leomon, Juri sinks into a deep depression that leaves her in a borderline catatonic state. Seeing his friend go from talkative and enthusiastic to mute and distant is enough to make Takato cry tears of despair.
- Downplayed with Switch in Sket Dance, who communicates via a speech synthesiser (which uses the same voice as him) on his laptop but is otherwise an Elective Mute. His refusal to speak came about in his Dark and Troubled Past; he feels responsible for his younger brother's death and was left so traumatised by the incident that he eventually stopped going outside altogether, let alone speak to anyone. He eventually gained the courage to come back to school and socialise with everyone but didn't feel ready to start speaking yet, and that's where his iconic speech synthesiser (created by his late brother) came in. In the present everyone takes his speech synthesiser communication in stride, but a few occasionally worry about him since they're aware of the negative implications behind his muteness. Switch speaking again in the last chapters indicates that he's finally moved on from the tragedy and feels at more ease with himself.
