After twenty years in exile, Irena, living in Paris, and Josef, a widowed veterinarian in Denmark, return to post-1989 Prague and meet by chance at the Paris airport. Irena remembers their brief flirtation before emigration in vivid detail, but Josef has no memory of her and hides this. They go to bed together in a Prague hotel, and when Irena realizes he never knew who she was, she is humiliated; Josef flies back to Denmark, leaving her behind.
Nostalgia joins the Greek nostos (return) and algos (suffering), meaning the pain of an unappeased desire to return. Through the Spanish añoranza, which traces back to Latin ignorare, it also becomes the pain of not knowing what is happening to the place and people one left. The longing is aimed at a home frozen in memory, so it cannot be relieved by physically going back, because that home has moved on and no longer exists.
When Odysseus reaches Ithaca, no one asks about his twenty years away, and Irena's Prague friends likewise refuse to hear about her émigré life. Those who stayed accept the returning exile only by erasing the time spent abroad, treating it as if it never happened. Return therefore requires an amputation of the life lived elsewhere, and the 'Great Return' becomes a second exile.
Memory retains only a minute fraction of lived experience, and each person keeps a different fraction of the same events. As a result, two people who 'share' a past do not actually hold the same past, so intimacy built on assumed common memory rests on an illusion. The asymmetry grows with emotional investment: the person who cared more remembers more and is wounded when the other has forgotten.
