@danielle As far as I'm concerned, (which is obviously a very small sphere of influence, sorry) you are always welcome in my bathroom. You're not an intruder unless you're the little kid shouting "Do you NEED your privacy?" while getting ready to crawl under the door, and even then, how polite are you for asking first? Aww! That's why there are stalls, so we can mind our own business while we do our business.
