In my country, we take off we are shoes when we go home.
So it's polite to keep your feet clean before you come home
For this reason, the floor is warm in our country
I'm sure it's the same in other countries, but we are little careful when we go in to parents room
we are parents usually sleep in the bedroom, so it's a bit of a nuisance when we go in

In my country, we take off we are shoes when we go home.
So it's polite to keep your feet clean before you come inside.
For this reason, the floors are usually warm in our homes.
I'm sure it's the same in other countries, but we are especially careful when entering our parents' room
Our parents usually sleep in the bedroom, so it can be a bit of a nuisance when we go in
