Imagine the following situation:
A black & white detective film from the 40s or 50s.
It is night and it is raining. From somewhere in the distance you can hear a police siren passing by in a large city.
The detective (who wears a long trench coat and a hat like the detectives at the time did) is standing under a sole flackering street lamp and is trying to light up a cigarette in the rain.
After he manages to do so, he starts thinking (ergo monologue :P) about the case and the clues he has.
If I managed to bring you to imagine this scene then I was successfull.
If not.... well... I hope you still liked it.
