Now could be a really good time to mess up her gathering. Or you could just introduce yourself as you

I can't believe she made you do that, OP! But at least that means your place must be ten times cleaner than hers if she wanted to use it instead.

sorry but i guess she's just not confident enough of her own image to act as an independent hostess and homemaker so she needs your guidance and she's too afraid to introduce you bc she's scared you'll steal the limelight

Pretend to quit in front of everyone.

Start blatantly stealing shit in front of everyone

Tell everyone what a terrible boss she is and see if anyone else tries to hire you as their maid.

Do her work and then when someone hands you a piece of clothing yell "Dobbie is free!!" and run out of there.

Act annoyed and loudly complain about having to unclog the toilet again ;)

Just destroy everything

just pretend to do it and then start destroying everything
