Grids Everywhere!

I was walking across a parking lot yesterday 

when I happened to notice the buildings to my right. 

The patterns of rectangular grids had always been there,

but yesterday the buildings seemed to stand shoulder to shoulder,

showing me how their bricks, mortar, cement and glass

had acted to make them alike, yet different.

All I had to do to get them to align themselves

was to shift myself a bit. Though rooted in place, they 

stood quietly, as if they wanted their differing eras 

and functions to be recorded at that moment.

But why was it I hadn't noticed them before?

I'm anthropomorphizing, of course, but I did 

silently thank them before moving on.
