Your story relates how I felt when I first started giving presentations about work I had done or about information I needed to pass on. I would get up in front of the audience and my mouth would dry up, I would start hyperventilating, and I would start talking really fast.
Like Lucy, I had the person in the audience who was judging me, my boss, but he wasn't the shadowy figure that Lucy had.
I'm not quite sure what to make of Lucy's shadowy figure. It could be her subconscious checking on her performance. Or, it could be someone in the past judging her performance. I don't know.
And that's what makes your story so intriguing. I'm left with two observations. One is, in spite of her apprehension, she made a successful presentation. And two, who is the shadowy person and what happens now that the presentation is over?
Your story meets the criteria of "Leave them guessing, just a little."
Your story is well written, easy to read, and kept my attention all the way through.
Thanks for your work. Keep it up.
