Asymmetric tree

This the end of a road that I regularly have to drive down. The eagle-eyed amongst you will have already noticed it's a cul-de-sac, so this is where I turn 'round.

Today, for the first time (in thirteen years!), I noticed its asymmetry.

And I thought to myself, "Hell's teeth, I'm busy at the moment and that's probably the most interesting thing I'll see today: I'll get my camera out".

Soz.
