Who make themselves at home at your house?

Maybe my older sister will make herself at home at my house.

I think my older sister makes herself at home at my house.
She lives near my house. nearby
It will take 20 minutes to walk. It takes 20 minutes to walk there / It takes 20 minutes to get there by foot.
When we were young, we used to fight a lot.
And then each of us was married, has a baby, raise a child... And then after each of us got married, had a baby, raised a child...
We become familiar. We became closer.
We share joys and sorrows of life.
We share food, too.

I closely resemble her.
I 've heard a lot (of people asking) , " You, two, are twins!?"

My sister and I visit each other often.
So my sister makes herself at home at my house and I make myself at home at her house.
