In unexpected places and times.
I visited a friend (in the hospital) who had just given birth.
I did not go alone. My neighborhood followed me on the whole way.
My participation in the conversation ended pretty quickly, because there are too many people in the group.
I had plenty of time to watch the play of light and shadow on the stairs where we stood.
I did not have a camera because it is cumbersome for such occasions, but the mobile phone is used well to capture the moment. The rest is achieved by cutting portions of images and combining them.
