I just saw this question after answering one about what I'd do if someone showed up unexpectedly with the idea of staying at my house for a couple of weeks or a month. It never would have occurred to me that anyone would ever do such a thing. Anyway, no point re-hashing that other question and answer here...
Now, to the matter at hand (which, again, immediately follows the question I just mentioned):
Let me say this: Yes. In fact, I may even pretend to have moved out state with my new fugitive, live-in, psycho, boyfriend. Better yet, I may find a way to pretend that I'd run away from the aforementioned boyfriend, that he was still living in my house, and that he had two mean dogs, a wild and rabid pet squirrel, and a Black Widow spider collection in the guest room.
Oh, OK. I'll give a more serious answer.. Yes. My bathroom is a great place to hide whether someone shows up at the front door or back door. Also, there's been a time or two when I've been on the sofa and not been able to get to the bathroom without someone at the door seeing me; and I've gone the route of slinking into a lying-down-on-the-sofa position, being as absolutely flat as I could possibly make myself, and remaining very silent until whoever it was went away. (By the way, all that drama for someone who just wanted to sell me some gutters for the house, but whom I just didn't feel like being bothered with. lol )
