How to describe someone that does not speak much? I know the words reserved/shy/quiet. But are there any positive words to describe these kinds of people? Like they do not speak much, but if they speak, they have a lot of brilliance in their words. How about if I want to describe someone who likes to hide their feelings and do not like to talk about his own personal things to others? How should I call them? And someone who likes to express their feelings in front of others? Any adjectives I can use? I would really appreciate any help. Thank you. :)
