Agaghị m ebi n’ikpere mmiri were asọ na-akwọ aka.

Literal translation

I cannot live beside a river and wash my hands with spit.

Explanation

A river is right there, so washing with spit would make no sense. The saying points to an overlooked advantage.

When to use it

When a useful answer is close at hand.
