I loved Yejide from the very first moment. No doubt about that. But there are things even love can't do. Before I got married, I believed love could do anything. I learned soon enough that it couldn't bear the weight of four years without children. If the burden is too much and stays too long, even love bends, cracks, comes close to breaking and sometimes does break. But even when it's in a thousand pieces around your feet, that doesn't mean it's no longer love.

It would take a while for me to realise that each of my children had given me as much as they took. My memories of them, bittersweet and constant, were as powerful as a physical presence. And because of that, as a bus bore me into the heart of a city I did not know, while my last child was dying in Lagos and the country was unraveling, I was not afraid because I was not alone.

"OK, we'll tell her you dug the grave." It's the truth - stretch, but still true. Besides, what would be left of love without truth stretched beyond its limits, without those better versions of ourselves that we present as the only ones that exist?

I understand how a word others use every day can become something whispered in the dark to soothe a wound that just won't heal. I remember thinking I would never hear it spoken without unravelling a little, wondering if I would ever get to say it in the light. So I recognise the gift in this simple pronouncement, the promise of a beginning in this one word.

I am interested in the idea that people should be able to define their own happiness. It’s not just about fertility; we are often told that we need this or that to be happy. We need to be thin, rich or whatever. But maybe we should decide for ourselves what happiness looks like.

There is a strong view in Nigeria, as in many other cultures, that a marriage is not complete without children. I don’t agree; I’m wary of the idea that people have to have some particular functionality in order to be full members of society. I think it’s a very dangerous idea. Humans are humans and they are worthy of respect…

I wanted to look at the subtle ways that Nigerians interacted with the Nigerian state. One of the ways we survive darkness—and there’s a lot of darkness in this book—is to find reasons to laugh. Laughter in those kinds of situations becomes essential. It’s not a luxury. It’s not just something you do because you feel like laughing. It’s been one of the ways I’ve coped myself. I wanted to bring that to this book because it would be miserable if there was no humor…

I wanted to write about extended family systems. You have people you can fall back on, and it’s good. But what if you don’t fit into what is expected of you? If you’re a man, there’s support. If you’re a woman, like Yejide, there’s the expectation that you marry into a family and after a couple of years you have children, and you have a measure of power. I wanted to look at what would happen if you could choose to be what you’re supposed to be, and how the community, in trying to help you become what you think you should be, turns on you.
