Dyson knows that travel can be a bit hair raising!
My pre-departure thought process goes something like this. If a serial killer gets me while I'm traveling - a totally likely scenario, right? - then the next logical step is that members of the FBI Behavioral Analysis Team will come to my home to investigate. I don't want the Criminal Minds team to conclude that the serial killer was targeting slovenly women who are unable to organize their sock drawer.
Therefore, before I leave, everything MUST. BE. SPOTLESS.
