For my entire life, I have always been a triangle. Connected to my father and mother. My shape was strong and stable. Many of my friends were squares. They had siblings. Still others were pentagons. Or even hexagons. In rare circumstances, some people had so many points of contact, they were circles. But being a triangle was all I ever knew.
When my papa passed away, I became a line segment. It was hard to stand up. I had no edge. By removing one point, I lost a plane of existence! At least I am still connected.
Someday, not too too soon, I will be just a point. No connections left to me.
Ultimately, I will become a singularity. No dimension at all.
