This girl is ultra annoying. Her whole speech about wanting to be an individual in school - errr doesnt she realise that kids take the micky out of teachers that are too out there.

Add to that her scolding of the Goth Patrol in class - firstly she would never have been left in a class alone when it was her first placement / visit.

Thirdly - why the heck was a Careers Adviser taking a detention class?

Fourthly - why was Nancy let back into a school where she has so much history.

Fifthly - is there any course HCC doesnt offer?

she probably does realise that,but doesn't really care,as nancy is nancy...doesn't care about if kid's were doing that to her,as it'd just be immature she'd probably say.
and you never know she may have been left alone in her placement,i was on my trident in year10 and i can remember getting vaguely left with a whole bunch of year 2's for about 10min's.
and it is a soap so anything is possible!lol
