I'm going on my own then you bunch of bastards

I think the school nurse fancies me.
Every time I walk past her little office, or see her in the corridor, I see her looking at me.
She does look at everyone else as well, but still - I think there's something there.
She's got a very big arse and she doesn't smell too bad as long as you don't get too close.
The children have a nickname for her.
They call her "The Big-Bummed Stary Woman".
