Ascension in the Moonlight

I think the theme of Ascension in the Moonlight is that our experiences would feel empty without the ability to share them with others. In Winchester's case, the Reverend Paul Wilson and his wife Angela  physically shared his adventure as they all watched the Brazilian green turtles lay their eggs. He was also able to verbally share his travels with his tailor who emphasized Winchester's good fortune in meeting such generous people.
Initially, the author was unimpressed with the island's offerings stating that it "was so lonely that I almost shuddered," and describing the place as "hot, lonely and exceptionally boring." Winchester's negativity towards the island was even apparent when Paul and Angela wanted to see him off as he said, "they apparently had something planned," which I read with an annoyed tone. However as the story progressed, Winchester's outlook starkly changed.
"'Aren't we just the luckiest people? she said. 'Isn't this a privilege?' But that wasn't the half of it. There was more." Winchester fully agrees with Angela that he had a great deal of luck. In my opinion, his luck was not in his experience but rather in his meeting the Wilsons. The turtles, the comet, and the stories would not have happened had he not have fallen into the generosity of Paul and Angela.
Along with being around the Wilsons, Winchester was able to tell details of his trip to his tailor. "'You know, you are a very, very lucky man indeed. Lucky to be in such a place. Lucky to see such things. And luckiest of all to meet such very kind people.'" The tailor's words perfectly sum up the adventure. Winchester's journey would have stayed lonely and exceptionally boring without the Wilsons, and his tales would not have lived on without his ability to tell them to the tailor.
