On one of my last days in the office in Karatu, the director was chatting with her staff and when one of them offered to take care of a certain task, she inquired with a joking tone to her voice (because hey, she's the director!), "Promise?"
They said yes. And then as almost an afterthought, she asked, "By the way, what's the Swahili word for 'promise'?"
They paused. You could almost imagine the sound of shuffling feet coming from the room. She asked again.
One woman replied, "Well, you see that's a problem. . . . There is no word for 'promise'."
"Aha!" the director exclaimed. "That could explain a lot of things!"
Yep . . . it does.
