"Convent school" doesn't really mean that the pupils have any connection with the convent, HOWEVER - One of the best night's out I ever had was with a girl from a convent school for whom the event was a last fling before joining the convent as a novice.

Within an hour she had demonstrated her ability to drink more than the rest of us put together, then, just to make sure we'd noticed, she did it again.

My lasting memory of her is of her declarations of love for me as I held her over a basin before I too passed out from the experience. (sorry if that's too much information.) I don't recall whether or not she made noises as she glugged the pints.
