I'm with Alleycat. We get a lot of sketches submitted to our ten minute play festival. A sketch starts , runs and ends with no changes to characters and does not tell a story. There is no inciting incident, point of attack or climax. Some are very funny but seldom dramatic.
They are often life without the dull parts cut out.
In our festival we usually send them back with the note that they are sketches and not plays and offer playwrights the opportunity to make them into plays.
