Some months ago, I was buying fabric from a woman trader in Nigeria. I was offered a seat, which I took, the mark of a serious buyer.

We began discussing the types of fabric I wanted. She was bubbly, a great conversationalist. “In my other life, I am a teacher,” she said. This was her weekend job. “I am a teaching trader, not a trading teacher,” she said. “Teaching is my first love although it does not pay all the bills.”
