The desperate old slapper really IS desperate, isn't she? All she can think of that may get people on her side is sex-related, nothing else. After her disgraceful scene-stealing antics on the stairs last week she's tried a few confrontational conversations, which is the way to redeem yourself, but she clearly can't be bothered with the hard work and/or mental strain involved when more lying might work just as well.
‘I’m going naked’ + ‘I’m having my period’. It’s not great timing, but then she is far more stupid than anyone could giver her credit for.
