I only had my cell phone with me when taking the photo this afternoon. I came inside to fetch my camera. In those few minutes the clouds were there no more. The scene changed completely and not that dramatic any more and I lost the chance of taking beautiful photos of clouds.
I shared it with the children in the UK. This was where they grew up.
It didn't rain but it was forecast for tomorrow.
I like the geometrics of your patio window.
