X + y = z

X + y = z
it all seems so easy
substitute 1, 2, 3
and the answer should be
as simple as ABC

but life's not all numbers
and letters
or shape and size
everything is not even or odd
a square root does not make you wise
and 3.14 does not sound like a God

so x + y does not equal z
everything is not easy
we're neither 1, 2, or 3
the answer will not always be
as simple as A, B, or C
