Secur, I don't dare bring this up with her, our finacial position is so precarious at the moment that i am petrified of losing my job. I just really don't want to be treated badly this afternoon. \\\\\it's making me miserable just thinking about it.
Colditzmum, thats shocking
I wouldn't confront her with it at all, just go in and breezily ask when its been rearranged for, or if its already been rearranged, comment on it, but act like its no big deal you didn't come in
She sounds batty
Maybe she is just in a bad mood but even so she is in the wrong. Make a note of this, the date, the time she called you, etc., in case you ever had to defend yourself in a tribunal. Best to always keep records as you never know.
I'd be irritated. You don't need to explain yourself or the importance of your children. I would heed the advice to just go on acting like it's no big deal. But, definitely take a not of it just in case you need it.
