There's a proverbial story:

Villagers on their way to the farms one early morning saw the tortoise sat on the back of his in-law pinned to the floor.

They asked him what happened and he said his in-law owed him a huge amount of money for over 15 years and had failed to pay.

“That’s too much and for too long - this one is a terrible in-law!” The villagers concluded, “deal with him very well. This in-law doesn’t wish you well at all, what you’re doing is very much justified.”

And so the tortoise felt vindicated and the villagers left to their farms.

By evening as they returned, they saw the tortoise on the back of his in-law, pinned to the ground.

They asked him what the issue was and he told them the same thing - in-law was owing him a huge amount of money and had failed or refused to pay for such a long time.

The villagers were furious and called the tortoise a mad fellow. Reminding him that an in-law was to be treated like a god, no matter what.

Did the tortoise want to kill him? What if the fellow did not have money to pay back, will his dead body pay the money in the afterlife?

So was the tortoise shamed.

And that birthed the Yoruba adage: “Alo ni t’ijapa, abo ni t’ana re”, meaning “the tortoise was vindicated as they went, but his in-law was vindicated as they returned.”

There’s a lesson on there I’m sure, not just certain what it is or is for.
