What do you think of the quiet people in life?

I don't just curious I guess. I'd prefer more vocal people to answer this, I'd like to see their opinions. Do you find them annoying because they prefer not to talk as much? Do you find their quietness to be a turnoff or intimidating? Would you rather befriend a quiet one if you are the loud one? Just give me thoughts, brainstorm, write me paragraphs if you feel you need to. I'm open to anything!
