if anyonegets really worried, they can always put child gates around the door,
Actually, I did, sort of... I made this thing when I moved in here:



I only set it up when I plan to go out... It cannot hold them back, but I should notice when they pass this "gate". It was much easier in the old apartment. There, you first entered a tiny little hall, and from there, you entered the rest of the place. Pretty safe.
