Demonstrative Speech? I have to DO something? In front of PEOPLE?

Well, having hurdled the descriptive speech...

What am I supposed to do for a DEMONSTRATIVE? What do I DO that I can show to others?

Maybe I can try demonstrating how I come up with an idea for a story or a character or just ideas in general?

Show them how to make my chocolate chip cookies? What else do I doooo?!

THE LAZY WAVE STRIKES HARD.

(Seriously, wtf am I gonna do, here?)
