Might I point out that you don't have a plate glass exterior wall in your shower,
True. It's clear perspex.
and you do have drapes over the windows in your living room & bedroom
No I don't.
and hopefully there is a door between your toilet and the rest of your house.
There is, but it stays open. Well, OK, I shut it to keep the roomba out if the floor's wet. And occasionally for guests.
But I do have locks on both front and back doors, and indeed a burglar alarm. Nothing to hide, but just possibly something to fear?
