What do you see from where you stand?

In my early years as an artist, one of my first lessons was the subject of "perspective" - how a viewpoint can change, all according to the point in space and time it is viewed from. The goal of understanding this idea was to gain some grasp on the imitation of reality -- how we as artists can betray the eyes with a trompe de oiel (I took Spanish, but I think the spelling is correct).
We each would like to be the central point from which everyone views the world, but this is not the grand design. We must occasionally view our worlds from the vantage point of another, and whether or not the two worlds combine is the whole point of perspective in the beginning... to know if two worlds can collide in the same spectrum, the same viewpoint, so that the tracks or highway leading to oblivion heads in the same direction.
Apparently, we don't always see the same as another - and interpersonal conflict emerges. I guess what we need is a 'change in perspective'...
An innocent bystander can see a vicious crime as murder, whereas the one attacked may see it as self-defense. A jealous lover may feel betrayed, when the loved never wanted the emotion to begin with...
