1. You can’t say anything without saying “by God’s grace” first.
It doesn’t take long for the locals’ way of speaking to rub off on you. If someone asks you how you are doing, you say “By God’s grace, I am fine,” or “By God’s grace, do I lie?”

A machete is as universally useful as duct tape. They are used for everything from farming, to pencil sharpening, to getting rid of snakes, to cutting up a chicken for some tasty jollof rice.
