Because it’s not there.
Just because it’s not there,
We don’t have to care,
But we know that we probably should.
We all can ignore,
What’s not at our door,
But that won’t do anyone good.
We don’t always know,
Until we are shown,
That problems exist at all,
Just because we’re not there,
We can’t just not care,
As ignorance can be as cruel.
