i appreciate we all know her stories are fabricated bullshit, given all the supposedly "candid" photos that steve has spontaneously taken of her in the bath and the shower - always featuring margot - babs regularly uses the bathroom with the door wide open!With the door open. Who uses the toilet with the door open?!
the kids are no longer toddlers thus presumably don't interrupt her, so i assume she leaves the door open specifically so she can claim that the kids walking past the bathroom evidence the title of her book; that she will never pee alone again - even if it's a situation fully prepared and staged by babs.
