Dave1812Dave: We have two bathrooms (neither in the main bedroom). Locking the bedroom door would be considered rude and, also, it is a shared space (as in two at a time, both your clothes are there, a tv, and so on.) One of my points about 'sanctuary' is that is is not a communal space; it is one at at a time and a locked door is practically mandatory. That makes the space kind of sacred; a hideaway. People leave you alone when you are in there (unless, as you alluded, there aren't enough of 'em to go around."
RDowns: very funny. Of course advertising this to your spouse and friends takes away the stealth pleasure of parking your carcass with your device--my that sounds a bit lude, eh?--and, possibly ruins it for the future, as in, "Hey, it's been an hour! I know you're surfing in there...get out now!"
