It may be every teacher's secret fantasy to have a quickie with their beloved in the staff common room during parents' evening, but having the governors walking in and interrupting is not normally part of the equation (unless you're really kinky). When this happens to Charlie, he rapidly finds himself without job and fiancee. A disaster...or a new beginning? Charlie plays the field - and the field wins. Retreating to lick his wounds he returns to his biology textbooks and considers the nature of mating - why do we do the things we do. Darwin, Dawkins and the London Zoo gorillas all provide inspiration. And after some thought, he begins to implement an entirely new set of courtship rules.
