One week later, I was discharged from the hospital.

My sister and I discussed and decided to move to the next trial site.

Before moving, we went to our mother's house together for dinner.

Mom always said on the phone that I had suffered and needed to take good care of my health.

I set the table, poured the drinks, and went to call my sister for dinner.

I couldn't find her anywhere in the house.

"Mom, it's time to eat. Where did my sister go?"

Mom looked at me in confusion, "Child, did you hurt your head? I only gave birth to you, where did this sister come from?"
