Shadow then light then shadow again

In the winter, I walk along a splinter of cold pavement.  I exit a warmed up work space and enter another warmed up space at the other end of that shard of unrelentingly harsh cold wind swept street.
In the summer, walking is a different experience. I weave in and out of streets, curious about people's flowers and properties and signs of growth. A street's shading or lack of it compels me to ease onto it depending on my mood. The shade and the sunlit ways alternately help me to regulate my atmosphere so that I can experience the splendour of summer at just the right temperature. Like pulses travelling through a circuit board, the shade and heat conduct my walk back home.
