I arrived late to Christmas dinner and froze when I saw my sister serving 20 people alone while her in-laws sat there laughing. When her mother-in-law threw a glass of wine over her head, I jumped up. “What did you just do to my sister?”

I showed up late to Christmas dinner, still catching my breath from traffic and mentally rehearsing my apology. But the second I walked through the front door, I knew something was wrong. Laughter spilled out from the dining room, loud and careless, yet there was nothing warm about it—it carried an edge. Then I spotted my sister, Emily.

She was rushing between the kitchen and the table nonstop, balancing heavy dishes in her arms, her cheeks red with exhaustion. Nearly twenty people sat comfortably around the table, and she was the only one waiting on everyone. Her husband, Daniel, lounged at the head of the table beside his mother and relatives, laughing as though this entire scene were perfectly normal.

“Emily, do you want some help?” I asked as I moved toward her.

She glanced at me briefly, tired eyes forcing a weak smile. “I’m fine. Just… almost finished.”
