My older sister. The most sensible one in the family.

When Mom and Dad argued, she would advise. When my younger brother caused trouble, she would shoulder it. When the family lacked money, she dropped out of school to work.
Last year, she got married. The groom's conditions were average. Dad said, "I've spent quite a bit on your brother's education, so consider this a dowry."
She smiled and said, "It's okay."
On the wedding day, I helped her pack her things.
I found her diary from when she was eighteen.
The last page.
"Today Dad said, 'You're still so sensible.'"
"I want to ask, can being sensible be exchanged for money?"
Below was a list.
Brother's tuition. Her salary. Money sent home each month.
Adding it up, it was enough for her to finish college. There was still thirty thousand left.
At the toast, Dad drank too much. Patted her on the shoulder and said, "My girl, I’ve never had to worry about you since you were little."
She raised her glass. Her hand didn't shake.
That night, when I took her back to the hotel, she said something in the elevator.
"A sensible child is just one who saves money for the family."
The elevator doors opened. Her wedding dress was dragging on the ground.
