When moving around in his dimensionality, his only experience of others is when talking to them or running into each other. He can’t move forward or backwards around them, only sideways, up and down around them. Similar to viewing germs, on a slide, under a microscope. He can’t look sideways because he doesn’t enjoy that dimensionality. If he could, he would see nothing, because they have no depth.
The three dimensional being can can now enjoy an existence closer than that measurement than any two individual dimensional beings can enjoy themselves. The two dimensional and the three dimensional being now share an intimacy greater than any intimacy the two dimensional beings can enjoy within his own reality.
