My parents tossed my wedding invitation straight into the trash and told me not to embarrass myself, but the morning they saw me walking alone down the aisle at a $40 million Malibu estate, with cameras catching every second, they finally understood the daughter they treated like an afterthought had built a life too big for them to ignore.

The whole family was going to Disney World. My parents had been saving all year. The night before we left, my mother came into my room while I was packing, sat on the edge of my bed, put her hand on my knee the way you do before you say something kind.

We only have four tickets, sweetheart. And Shelby really, really wants to go.

Four people. Four tickets. Dad. Mom. Shelby. And the space where I used to be.

I stayed with Nana June. She made chicken and dumplings and let me watch whatever I wanted and took a Polaroid of me on the front porch. I smiled for it — my mouth did, anyway. Eyes of a girl who had already done the math.

Somewhere in Shelby’s room, there is still a photo album from that trip. Matching Mickey ears. Castle at sunset. Shelby on my father’s shoulders.

There is no album from my week with Nana June.

After Disney, the pattern got easier to see, or maybe I just got better at reading blueprints.

Shelby’s dance recital: front row, both parents, flowers afterward.

My science fair win, regional qualifier: a text from my mother that said, That’s great, Han. No period. No exclamation point. Five words, thumbed out between whatever she was actually doing.
