Full title being : For I Have Lain Me Down on the Stone of Loneliness and I’ll Not Be Back Again.
Clever story of alien oppression and response to it, cunningly done by setting the story in Ireland, a place with a long history of having to deal with forces of occupation and oppression. An American who is on the emerald isle as the last leg of a world tour prior to taking the opportunity to leave the planet, finds that his is a journey that has been done before, as there is a diaspora of those who have left, never to to return. It looks at the emotional impact of dealing with/living with the alien, whereas most SF of this type will deal with violent revolt and overthrow.
