Well.. This girl sure made a very big mess of things.
Her "prince charming" wasn't available to go running to whine about mean old master, so she was forced to look at her actions instead.

She was a total bitch to her master. She disobeyed and was incredibly rude, and outright challenged him, along with arguing with him.
It doesn't matter what she thinks. It matters what HE thinks. It doesn't matter if he decides that "pillow" is an offensive word, or that he wishes her to speak only in Portuguese from now on. Her response should be, "Yes Master", and she had better get in gear learning Portuguese!

So.. Irreverent and offensive humour are no longer tolerated. Speaking without carefully considering her words is no longer acceptable, if it really ever was. This simply means that she had better brush up on her polite and non offensive language skills.

It is not about being "PC". It is about showing proper respect to all. Master's views on this have apparently become more stringent, and so, her actions must reflect what he wishes to present.

She is a slave and she belongs to him, until such a time as he wishes to be rid of her. Then she will belong to whomever he sells or gives her to, or to the next master to take possession of her, should he simply discard her.

She also had NO right to try and dictate to him how he will use her in doing HIS shift for the Pool Party. She is not staff for that event and she knows it. She is the property of staff, to be used, by him or by the EC, as he sees fit, so that "we are on staff" bit does not fly. She is the driver of HIS van, for HIS pleasure, at HIS whim or will.

To refuse to drive him to HIS home was inexcusable as well. She would have been perfectly willing to drive almost the exact same distance to go running to her lover, had he offered.

This girl will now retire to the floor of the Mistress' room that she is permitted to sleep in, and see if a night or two/few spent there will do her memory any good. She hopes that it is not too presumptuous of her to use the dog bed and pillows and comforter. She may report to Mistress tomorrow evening for counsel.. and also to beg for the lash.
