Yes, Noggin....you are quite right.
A student is perfectly entitled to learn night flying during the JAA (and FAA) PPL syllabii.
However, you missed the point of the sarcasm - there can be no jutification for an instructor taking a student on a night flying exercise when he (male, in this case) has only 13 hours of flight time.
To introduce the challenges of night flying to a student who has not yet learned how to even land the aeroplane properly - and is unlikely to have done his first solo (though possibly) - is just not professional.
Night flying requires navigation skills and instrument flying skills - and the landing references may well be different.
To take a student on a night cross country at only 13 hours is a disgrace. It is a waste of the students money and the only purpose it can justifiably serve is to get another hour on the instructors time sheet and log book.
