There is a Conservative School of Rhino Thought that proposes that each RTot is born with an invisible identical twin Self. This idea explains why RTots never seem lonely; each has a playmate that knows that Tot every whichaway. Comforting and stimulating companionship.
The Liberal School of Rhino Thought proposes that each RTot is born with dozens of invisible twin Selves.
If We Rhinos better understood how numbers work, We would wonder if both schools might be right?
