Once you start thinking about something that flows, glacial ice for example, you can’t help but think about other things that flow: Rivers, honey, molasses, air currents, clouds, particles, people, a herd of animals.
I love seeing and watching clouds. No two look the same, they are always changing, you cannot hold one, and they are there for everyone, no matter their age, location, status, or schedule. This is one of the last sunsets I saw from my flat in Wellington, New Zealand, you can see one of the arms of the turbine on the horizon.
