Anyone can write five people trapped in a snowstorm. The question is how you get them into the snowstorm. It's hard to write a good play because it's hard to structure a plot. If you can think of it off the top of your head, so can the audience. To think of a plot that is, as Aristotle says, surprising and yet inevitable, is a lot, lot, lot of work.
