It was as if nothing could spoil our fun on this gloriously sunny day – until we realised that it was impossible to drive across to Holy Island by car when the tide was in. SL made a weak attempt to crest the waves before I persuaded her that it really was time to turn back. We passed DT and JLW on our return and advised them to do the same.

Meanwhile I wondered whether I would get into trouble for neglecting a PhD student in favour of a quest for aftershave?
