Ancient ranting

Listen carefully, this whispers means something.

Its not just spoken randomly
The wise do select words wisely
there within there intelligence bank
lies words to bring positive change back
The white hair is a good sign
the good sign, Of experience passed by
Lots of wisdom they've to give out
Because there is always lots to remember
so wait a minute and open your brain
here come a chance to get wisdom in cheap bargain
Just a little of your time and there it will lie in state
Ancient ranting
The old folks chanting
This is not a piece of slippery parting
Nor some kind of stupid barking
but for the wise there lies some lessons
And those not, it still will be the ranting
The old nasty sayings
equalling to nothing.
