In the case of plus C, C is not real.
Well, it’s real, but not really something, see?
You’ve got to tack it on to ev’ry deal,
Like thank you or a handshake or a please.
*
It’s not, like, fake, it’s just necessary.
An acknowledgement of arbitrary!
A constant filled with nothing, quite airy,
But there all the same, needless to bury.
*
We can define it, can choose what it means
But it must be there or the sum is moot.
It must stay empty, for some number’s genes.
But it will be there, capital and brute.
*
C by nature is undefinable;
Still, doesn’t need to be assignable.
