Screenwriting (3) - Third idea

After starting to write my phone call idea and it not flowing very well, I talked to Barry Conway and he gave me a good idea for a short film with an entertaining and not too complicated punchline. A hallway much like in Friends

with an additional third flat where a wall on the opposite side on that picture would be. To the growing annoyance of the inhabitants of the left and right flats there is a bin bag lying in the middle of the hall. Jack thinks it belongs to his neighbour on the opposite side of the hall, Julie - who he hasn't met and vice-versa.
After some impersonal quarrel over whose bin bag it is and who should take it away, both Jack and Julie observe the previously unknown third neighbour taking the bin bag out, leaving them standing in an awkward position.
