The potion of eternity

Nethra! Don't take that coat. It is too delicate. Her Grandmother's warning appears weird for a moment.

Why does she obsessed with an old coat which is not even good for wearing at least once in a while?

Grandma, what is in the coat's pocket? Nethra questioned.

Grandma's eyes became furious. Have you seen it? She asked.

The 

There is a small bottle in it. Nethra answered and gave the bottle to Grandma.

Grandma took it and kept it close to her heart.

This is a portion of eternity, Grandma smiles.

I don't get it. Nethra said.

It is a potion made with magical elements and it makes you eternal on the earth. Grandma said history behind it.

Nethra became confused.

But,.. she murmured.

I know your question. It was not worked on your father. Grandma's eyes became wet while saying the words.

I believe it works for you soon. She nodded her head.

Grandma, is there anything I need to know about the death of my father? Nethra asked hesitantly.

Grandma looked over the wall which has hand marks on it.
