Uncle Chest, Weekly Short-Short Note Prompt, 519 characters

It was truly sudden.

When my mother creaked open the bottom drawer of my grandmother's heirloom chest, he popped right out.
A middle-aged man wearing a kimono, he said with excessive politeness, "Pleased to meet you. I am an uncle."

"Pleased to meet you. I am an uncle."

My sister screamed, and my father tried to call the police, but my mother was strangely calm and, of all things, brewed him some tea.

It seems that uncles have possessed this chest for generations, watching over the family.

The night before my sister's job interview, the uncle said, "A navy suit is best. The interviewer likes blue."
As a result, my sister won a job offer.

When my father was struggling with a presentation for his promotion, he said, "Put one meaningless slide in, and if it comes up, just skip it. It makes it look like you have time to spare and are in control."
For some reason, that was a huge hit, and my father was promoted from assistant manager to manager.

And then, on the night I was worrying about whether to confess to the girl I liked, the uncle poked only his face out of the chest and said this.

"Don't go out of your way to call her out; just talk to her casually on the way home."
Strangely enough, there was a moment when she was alone, and I managed to confess. The result was, well, decent.

And then one day, he suddenly disappeared.

On the morning my sister got married, there was a small note left in front of the chest: "Sis, I'm worried about you, so I'm going over there."
My parents and I stared at it in silence, and then we laughed.
