Is a shy person and a quiet person the same?
Not necessarily, a person who is quiet, may just chose not to talk much. They may feel that speaking up just ends up in a argument so they say nothing. Or they may feel others won't value what they have to see.
Not exactly . A shy person is exactly that shy . A quiet person just prefers to be quiet , but is not to shy to approach or talk to people .
A quite person can have any reason to not talk like if the person lost their voice but a shy person just has one reason to not talk.
