My grandmother and I were very close.

When I was a child, I spent almost every summer at her old countryside house. It was a quiet place filled with antique furniture, old books, and the smell of fresh bread she baked every morning.

She had many stories about our family.

But there were always certain things she refused to talk about.

Especially the past.

A few years ago, when she was very sick and close to the end of her life, she asked to speak with me alone.

I sat beside her bed, holding her hand.

She slowly reached under her pillow and pulled out something small.

It was an old key.

Small, bronze, and very worn.

She placed it in my hand and closed my fingers around it.

Then she said something strange.

“One day you'll know what it opens.”
