Furry Fright

I was a bit distracted and didn't really take a lot of notice when the lady got into the back of the taxi and asked to go to town, on the way she asked me to pull up outside a post office while she did an errand.
 I was just sat there daydreaming, when out of the corner of my eye I spotted something small and furry making it's way from in between the seats towards me. I was out of the car quicker than a Danish cartoonist leaving a mosque.
 I crazily thought maybe a rat must have gotten in somehow. Just at that moment the lady walked back up to the car and seeing my expression guessed what had happened,sorry she said I should have told you, I had my Yorkshire terrier in my pocket and thought it would be okay to leave her in the car.
