In this scene, Trevor really needs to use the bathroom but he doesnt want to go outside to use the outhouse because it is pouring rain outside and he doesn't want to get wet. He wants to do his business in peace. So he then thinks of other ideas.
Sigh, I really need to use the bathroom but it's raining outside and i'd have to use wet newspaper to wipe my bum.
ah ha! Why bother going outside to the outhouthouse at all?
I can just put some newspaper on the floor and do my business like a puppy!
Ahh now this is really great, no stress, no soggy newspaper, I'm really enjoying this!
Whos there? Hallo? Hallo?!
Oh no! I better finish this as quicly and quietly as possible!!
Is somebody there?! Trevor, is that you?! Frances? Hallo? Hallo?
Ok i'm finally done! I will just fold up the newspaper and place it in the bottom of the rubbish bin. Mission acomplished!
