I have to say, though, Ginty's reaction to the letter is quite reasonable - having presumably heaved huge sighs of relief that she hasn't managed to get herself or Nicola expelled it must have come as a nasty shock to realise she had managed to get Patrick the boot and failed him his 'O' levels (as we find out in RAH) into the bargain. No wonder she goes into a flat spin and bolts to the other end of the country.
