who knows?

Mr. Sai lost his horse and when his neighbours commiserate with him he says "maybe bad maybe good, who knows?"

Then the horse comes back, leading another wild horse. His neighbours rejoice for him saying how lucky he now has two horses. He replies again "maybe good maybe bad, who knows?"

His son breaks his leg, and again the same gets played out, "maybe bad maybe good, who knows?" Then the army comes to town, but the son cannot be pressed into service because of his leg.

Maybe bad, maybe good. Who knows?
