Taking Advantage

A busy day; pleasant enough really, but a bit grey at times.
I was full of great intentions but none came to fruition.
Walking back to my car, I noticed a Buddleja bursting through the railway wall.
I remember seeing a photo series of what happens when man leaves places alone; how plantlife and animals find a way to flourish and reclaim the environment.
Slightly concerned about what the roots of this bush will do to the wall in time.
However, for me, the burst of colour and the impudence of the bush, made the grey day a little brighter.
