One Scene Play

My one scene play is about to drive me insane. I'm trying to meet my word limit of at least 800 words. But with my basic plot, it's hard to have a lot of dialogue. I don't know if my teacher that I have to write this for will count dialogue and the 'setting the scene' paragraph or if only dialogue will count for my 800-1200 words. I've asked and am currently waiting for a reply. We shall see.....
