I actually encountered an old man climbing over the chain-link fence at 22nd Street Station in San Francisco. The rest is imaginary. Except, of course, for entropy and the heat death of the universe. Those are real, I’m sorry to say. My father really did try to explain difficult physics concepts to me when I was ten or so. Not the heat death of the universe exactly, but I remember a long discussion related to the conservation of energy. As a ten-year-old, I contended that if I put some heat in the freezer, I could destroy it.

My job allows me to be around smart people with diverse interests, which is great fun. I can skip across the surface of many fields, rather than focus on just one. The kernel of this story was a financial oddity that I found intriguing: the strange fact that student loans are the only major loan type that isn’t collateralized. It’s obvious why, of course, since you can’t repossess an education. But what if you could?

The bird’s been nesting in my brain since 2009, and this is the seventh story she’s in, but before this, humans were always part of the intended audience. So this is me exploring what mechanicals might say when we’re not around—which is a deliberate mirror on marginalized human experiences, but it’s the only thematic aspect that was deliberate. My conscious brain isn’t in charge of that stuff. I was just writing in December 2016-February 2017, as a chronically ill non-citizen US resident with many friends in scary situations.

I experienced a lot of that bullying you mention when I was young. I was someone who was perceived as a weird, feminine boy, and in the 1980s and early 1990s that was a very hard thing to be. There are many stories out there about LGBTQ people dealing with this awful, crushing weight of difference and exclusion and violence. I think, though, that it’s important to have stories that are not dark and brutal.

Exploring otherness is, I think, the essential work of the fiction writer. We develop our skills by sitting on the outside edges and observing; we create people on the page who are not (to the extent that we can help it) ourselves. The better we are at creating not-us on the page, the better people think we are at writing fiction. This is all very lovely and twisty, because of course, we can’t write anything but ourselves.
