A relative's daughter in her thirties finally got engaged, and the whole family was happy.

A few days ago, they suddenly said the wedding was canceled.
I inquired about the reason:
The boy went to the girl's house for the first time to have a meal,
During the meal, an elderly man trembled as he came out from the inner room,
His hands shaking so much he couldn't hold the bowl.
The girl frowned: "Who let him come out?"
Her mother quickly pushed the elderly man into the kitchen and handed him a cold steamed bun.
The boy asked who he was, and the girl said: "My dad, with dementia."
