BSC (BatShit Crazy, the old lady I room with) and I haven't spoken to each other for almost 5 weeks, so she's taken to passive-aggressively putting dusty packages and mail on my pillow, even though for almost two years she's known there's a mail basket right by my door. I've taken to moving my puzzle table in front of the bed to block her, and today she walked past the empty mail basket as usual and climbed over it to put mail on my pillow. Again. At least she didn't wander by later like she usually does and comment on my personal items that she could only have seen if she's been walking around in my room. I know her husband will flip a bitch if I put a lock on "his" door and don't give them a key.

I asked my co-conspirator Mango if she thinks BSC is just too senile to remember that I've asked her 107x per month not to do that (dust+pillow= allergy attack), and she was like, "Girl, please ! She's acting like a child, trying to get you to go down there and yell at her because that's the only way she knows how to get attention." Which is what I've been saying all along. I try to ignore it, but I don't have enough pillowcases to make it through the week.

Should I:
1. spend what little money I have on renting a P.O. box that I can never access because the damn place is always closed before I get off work, but at least she won't have access to my mail and will have to pick some other stupid thing to annoy me

2. buy more pillowcases, which ain't cheap either, and ignore her until I get the fuck out of here (if I had money for pillowcases and mailboxes, I'd already be gone)

3. kill her and earn the undying devotion of FOG (Fossilizing Old Guy, her husband), assuming he even notices her absence, since he does all the housework and shopping anyway and watches tv alone while she hides in her batcave

or

4. build a more challenging obstacle course for her to climb past and call it The Total Batshit Workout ?
