Comment on If you have a circle of friends, then by definition they are all fringe

It’s really stupid, so prepare yourself for disappointment… Consider a circle, and then identify it’s fringe. Any point on the circle is on it’s fringe. Same thing holds if all your friends joined hand-in-hand to make a circle. Every one of them is a fringe element of the circle, because that’s what a circle is.

There’s an inside part of a circle, too.

  If we had a seperate word to mean an unfilled/hollow circle I would jave used it, bit alas… oh, wait a minute… a ring… dang it! Still not sure how I feel about the implication of friend-wedges, though.

    Mathematically, a circle is the outer line of a disk.
