I have a continuous dialogue with my two young daughters that the hallway in our building is not a private place but a place for everyone and it’s not nice to be loud and treat it that way. They are 4 and 2. So I do my part daily to raise them with respect for the world around them. However you can stop a 2 year old from screaming so it’s a daily venture. Treat the world the way you want to be treated.
