That wall looks very solid to the eye, and yet you can clearly see the bushes behind that walls, in a hazy, abstract way. that's the most alluring aspect of the photo for me.
another thing to notice is how at the upper left corner, behind the main wall - you can see a blue wall, a part of some building probably that in contradiction to the main wall is completely solid and unyielding to the warm lights.
You meet a person, there are those you might like and you might hate, and then there are those you just won't remember, they didn't make any impact on you.
there is something that makes you remember some people for a long time, yet you cannot define it - it is their "personality", an elusive concept that melts when you try to describe and define it in words, and it's not your fault - a person's personality is not something that can be defined in definitive details, it's the whole of the things combined and some more - and this "more" just can't be described by words. think about it - if I will tell you to describe a person you love and write all of what you said on a paper, would you say that after reading this definitions you wrote I know the person? of course not!
this Is just like the walls - there is a wall you can see and describe yet there are blurred objects in the background you can see that make it so attractive yet you can't really define what this objects are, just like the "more" in people you remember.
And then there are those you don't remember, they are dull and irrelevant for you, you don't find anything undefined and mysterious about them, just like the forgotten dark wall at the upper left.

So express yourself fully people! be someone others will remember!
