Yin Yang

If there is one thing
That I don’t understand,
It’s got to be the Yin and the Yang.

Why do they have to be two?
Why can’t just one do?

Why are they even here?

To spoil the sunny days with heavy rain?
Or to spoil the heavy rain with sunny days?

They interfere a lot.
Because of them, me and lover fought!

It was all too good to be true,
Then jealous of the Yang came in Yin
And the whole thing blew!

I just don’t understand!
What’s the deal, with the Yin and the Yang.
