llatpog, your statements are ambiguous, based on erroneous assumptions, or just plan not true. I'll give you two examples:

You said, "If I take a circle (2 dimentions), I go from Point A to Point B, I will always end up where I started." That is not true unless points A and B are the same, in which case you don't have a circle.

You said, "If I take a Sphere(3 dimentions), and start at any point I will eventually end up where I started, but I will often come close but not quite where I started...as all my lines will not be parallel." First, you said, "I will always end up where I started". In the next sentence, you contradict yourself by saying, "but I will often come close but not quite where I started."

Hopefully, you can fix the problems in your contribution and try again.
