One said she could not abide to be with anyone with degrees in geology, the landscape or the island itself. It's possible that our would-be castaway was herself an expert.
Nothing is more distressing than having to listen to someone else's research.
No doubt university lecturers are occasionally forced to discourse with someone from another department and one can imagine the mutual horror and disgust when a prehistorian meets an analyst of the benefits of globalisation. Stuck on an island, someone whose life work was finding out whether people drive or reverse into parking spaces might find listening to stuff about landscape a little hard. An example of specialist incompatibility nearer home would be the mutual incomprehension between archaeologists and botanists. These two often find themselves on the same field trips because of their forced juxtaposition in county archaeology and natural history societies. Generally the archaeologists are off over the brow of the hill within minutes of the coach stopping, to find on their return two hours later the botanists still enthusing about trifolium glomeratum on the lay-by verge and muttering about how one of the archaeologists was definitely seen cleaning his boots on the only example of hymnenophyllum tunbrigense found outside Kent.
