I couldn't read but I could talk

I'm hyperverbal so I always got into trouble for asking too many questions in class. I would even ask questions I thought I knew the answer to if other people in class looked like they didn't understand something because my older sister had a fear of talking to people especially in class, I couldn't talk for her because we didn't have the same classes but any other time she'd make me talk for her, so I think I just start doing it for the people around me too. I couldn't read but I could talk.
