Relacionado con la pandemia, encierro y aislamiento, el trabajo aísla una manifestación clínica a partir de un recorte del relato de un paciente en sesión, quien dice haber contactado en cuarentena a una ex amante a la que hacía años no veía ni hablaba. Lo primero que recibe de parte de ella como respuesta es una pregunta acerca de qué le pasa a los hombres con la cuarentena que todos tienen ganas de rememorar viejas historias… Con dicha reacción ella lo coloca en una serie de varios, y él siente que es uno más entre tantos, situación que lo altera profundamente. Pero a partir del relato, se intenta traer una serie de preguntas y cuestionarlas: ¿a partir de la cuarentena se verifica un aumento de número de sujetos intentando contactar a ex-amantes?; ¿es efecto de la cuarentena que sujetos mas de-lo-usualmente-corriente estén contactando a quienes han tenido un lugar importante en su pasado?; ¿esto se da por encontrarse solos y aburridos?; o porque suponen al antiguo partenaire solo y aburrido?; … ¿es sencillamente esto?. Se ensayan varias explicaciones al respecto, sin excluir referencias de otros casos y aportes de distintos analistas y la consideración del caso por caso.

The first thing he receives from her as an answer is a question about what happens to men with quarantine that everyone wants to recall old stories ... With this reaction she places him in a series of several, and he feels that he is one more among many, a situation that deeply alters him. But from this story, an attempt is made to bring to light a series of questions and analyze them: during the quarantine, is there an increase in the number of subjects trying to contact ex-lovers ?; Is it the effect of quarantine that more-than-usualcurrent subjects are contacting those who have had an important place in their past ?; Is this because they are alone and bored ?; or because they suppose theirs old partners are also alone and bored ?; ... is just this?. Several explanations are tried in this regard, without excluding references from other cases, contributions from different analysts and the consideration of the case by case.
