I've been collecting leaves

Walking home ... what it is about autumn that is filled with nostalgic smells? The air is so cool and feels clear, the trees stencilled against a dark but light blue sky, the smell of smoke, washing, dinners, fallen leaves, grass ... the rustle of leaves as you navigate through them (hoping there's no hidden dog poo) and the array of colours, patterns and shapes on the ground ... like these.

Ah - autumn leaves
