The reality, for most of us, is that our debauchery consists mainly of eating and drinking rather too much; singing and dancing in a more flamboyant manner than we are accustomed to; wearing skirts cut a bit too high and tops cut a bit too low; indulging in a little flirtation and maybe an illicit kiss or fumble; speaking to our colleagues with rather less restraint than usual, and to our bosses with rather less deference – and perhaps, if we are feeling really wanton and dissolute, photocopying our bottoms.
