Instead of locking the door to your bedroom.....lock the entrance door to the house?......Lock her out of YOUR house?
If she don't leave....tell her you have a Mammy Kanga with one hell offa powerful kick to her.....lmao....maybe that'll encourage her.....(either that or convince her that urra loon?.......roflmao).
Seriously....tell her to get lost.....THEN lock the door. You DO have that right....and, ignor her blah blah...she's full of it...but you know that already.
I wuvz you...
