In a Landscape of having to Repeat

In a landscape of having to repeat.
Noticing that she does, that he does and so on.
The underlying cause is as absent as rain.
Yet one remembers rain even in its absence and an attendant quiet.   
If illusion descends or the very word you’ve been looking for.
He remembers looking at the photograph,
green and gray squares, undefined.
How perfectly ordinary someone says looking at the same thing or   
I’d like to get to the bottom of that one.
When it is raining it is raining for all time and then it isn’t
and when she looked at him, as he remembers it, the landscape moved closer   
than ever and she did and now he can hardly remember what it was like.
