I’m writing a play and my teacher told me to include something abstract. Help?

I know the definition of abstract. I just don’t know how to include it in a play.

Well first think of a plot and characters and storyline.

Once you come up with those, it will then be easier to add in something abstract later. If you try to focus on the abstract first, you’ll never be able to get the play finished.

Tomorrow I start filming in a movie where I play a teacher. My first time doing real acting for a movie. Tips?
