The Dishwasher
**Warning spoiler**
I liked the film but I was wondering about something. When Alex has cleaned the apartment she puts the scotch bottle she was drinking from and the phone she rang her ex on in to the dishwasher. Why not take the bottle with her and wipe down the phone? The police would then know she used the phone and wanted to hide her prints. Is it to show her fractured state of mind? Not quite sure.
