What if they’re tight-knit, or the fabric of the community? We all have a common thread.
How so?
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.
tl;dr focus on the locus
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, but 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.
If you are in the centre of the circle, that is.
With a circle you actually get the lowest possible ratio of friend-fringe to total friend-area, when compared to alternative 2-D friendship n-gons.
