Red leaf on yellow fall

I still remember the day I took this shot, it was a rainy day of the 2004 autumn. I was walking with my girlfriend near a park, over a carpet of yellow leaf. Then my eyes caught something different, something red.

I took a step back, I took out my loyal camera, and I grabbed this shot.
I still remember the voice of my girlfriend asking why I was loosing time photographing wet leaves... (but she appreciated the photo afterward :-)
