Two ideas

Once there were two ideas
That flowed together like rivers:
Said the first:
I am every drop of rain on the southern plain
Replied the other:
I am every flake of snow on the northern range
I am the greatest kingdom
I am the only queendom!
I am a population of populations!
My society is unique!
I have been here forever!
I am timeless!
And so they argued
Until their hair was braided
Into a beautiful waterfall
Really.
The only way is down.
