Esther locking the bathroom door

We grew up knocking on doors before entering the bathroom or a bedroom.

It bothered me too. I can understand that rule for a very young child. But a child as old as Esther? That's just wrong. What kind of 10 year old girl would be comfortable with anyone being able to walk in on them naked or using the toilet?

It seemed weird to me too, but I think the mother was understood to be a bit paranoid about the safety of the kids.

My parents never wanted my sister or me to lock the bathroom door when I was taking a bath/shower. To this day, I still don't lock it.

I lock it if I'm crapping because my little girl will come in if I Don't lock it, she follows me everywhere. I used to lock it while I showered but I'm diabetic so now I keep it unlocked in case of emergency. Other than that, no need to lock it.

It's a safety issue.

A family relative of mine once fell in the shower and broke a rib. She locked the door and no one was able to get into the bathroom to help her. Needless to say she couldn't move to open the door herself. The door had to be knocked down. Ever since that, I think twice about locking bathroom doors.

In house full of relatives, it isn't necessary.

I know this is years late but I think locked doors are different in familes. When I lived with my parents (whether as a 10 year old or 20 year old), you did not lock the bathroom door. Shut yes, locked no particularly when you take a bath or shower. Just a safety thing.

Most parents would take note of who is in the bathroom. And many sensible people do knock before they enter. As many have said, leaving the door unlocked is a safety thing, so the parents can help if there is an accident or cry for help.
Esther just wanted the to lock the door so the family members couldn't randomly walk in and see her scars.
