CVIII : Markings

Last week, before leaving work, I wanted to take a look at just how dusty and in-need-of-cleaning my car was, and I came across this lovely marking:

First thing that came across my mind was "WHY is there an imprint of a shoe on my car?!" It looks like a child's shoe print, small and cute, but what is it doing on my car? Who would climb onto a stranger's car? I didn't see any other shoe marks though. What the heck.

But overall analysis: My car needs a bath.
