The natural numbers start with 2 (TWO). The name "counting numbers" make that clear. If there's only one item of a certain kind, one doesn't start counting.
Moreover, for most mathematicians, counting stops at two as well, as anything larger than 1 is denoted by `n', which is synonymous with `many, I don't care how many'.
Consequently, 3 must be supposed to be infinity. The symbol for infinity is two 3's on top of each other. This explains the mystery of Trinity.
I hope this simple solution will stop the silly discussions about 0 being a natural number. My hope will be in vain, I know.
