Acid Rain

I don't know when I've seen clouds this dark --- BLACK! with white surrounding them entirely. Got em boxed in. No place to go, nowhere they can stretch out. Mama says she has! She's seen em so dark til they looked like black holes in the universe. Like spilled midnight. "Wonder what makes them that way?" I probed Mama, certain that she had the answer. "It's because they're angry. Tired. And probly curious. They wanna know what's outside of those white borders that has the sky so intent on keepin them in? Thinkin, 'surely there's space enough for them both---cloud and sky! So, the tighter the sky's hold on em, the angrier they get! The stronger their will to go beyond the borders. And I dunno how dark they gonna grow, nor, how long they gonna wonder ---But, I'm tellin you, Child it's gonna rain.
