THE BOLD AND THE BASHFUL

If I have to classify myself between introvert or extrovert, I don't know which one I am. Sometimes, I'm introvert, and other days I'm extrovert. When I am with my family and friends, I totally talkative, funny, and outgoing. On the other hand, when I talk with an authority, I get really nervous. Also, when I have a presentation at the university, I get really nervous, my hands perspire, and I get a terrible headache.
