Yet they were girls who knew what I meant when I spoke of “treeing.” We sat in my room (because, having so few travel items, mine was the emptiest) and challenged each other to look out at the stars and imagine the most complex equation and then split it in half and then in half again and again. When you do math fractals long enough, you kick yourself into treeing just enough to get lost in the shallows of the mathematical sea. None of us would have made it into the university if we couldn’t tree, but it’s not easy. We were the best and we pushed each other to get closer to “God.”

Then there was Heru. I had never spoken to him, but we smiled across the table at each other during mealtimes. He was from one of those cities so far from mine that they seemed like a figment of my imagination, where there was snow and where men rode those enormous gray birds and the women could speak with those birds without moving their mouths.

Once Heru was standing behind me in the dinner line with one of his friends. I felt someone pick up one of my plaits and I whirled around, ready to be angry. I met his eyes and he’d quickly let go of my hair, smiled, and raised his hands up defensively. “I couldn’t help it,” he said, his fingertips reddish with my otjize.

“You can’t control yourself?” I snapped.

“You have exactly twenty-one,” he said. “And they’re braided in tessellating triangles. Is it some sort of code?”

I wanted to tell him that there was a code, that the pattern spoke my family’s bloodline, culture, and history. That my father had designed the code and my mother and aunties had shown me how to braid it into my hair. However, looking at Heru made my heart beat too fast and my words escaped me, so I merely shrugged and turned back around to pick up a bowl of soup. Heru was tall and had the whitest teeth I’d ever seen. And he was very good in mathematics; few would have noticed the code in my hair.

But I never got the chance to tell him that my hair was braided into the history of my people. Because what happened, happened. It occurred on the eighteenth day of the journey. The five days before we arrived on the planet Oomza Uni, the most powerful and innovative sprawling university in the Milky Way. I was the happiest I’d ever been in my life and I was farther from my beloved family than I’d ever been in my life.
