Leaving a mark

On a road near my house, if you pay attention you can see this...

This always makes me smile

For some reason this simple detail makes me smile. It also raises so many questions in my head. Why didn't the person that was painting the line remove the leaf? What happened to that leaf? How long will this mark stay there?

It's such a tiny detail but it makes that otherwise boring stretch of road very interesting. For me at least.
