E greu aici, pe Pământ. Și nu doar în România. Devine dificil să fii om. După mii de ani de evoluție, exemplarele acestei specii se văd nevoite să lupte pentru ceea ce credeau că au câștigat o dată pentru totdeauna: drepturi egale în a-și căuta fericirea. Se văd nevoite de a repeta istoria și de a se întoarce în momentele ei cele mai întunecate. Poate că în altă parte, e mai bine. Poate pe vreo planetă îndepărtată, aprope de capătul Universului, ființele au descoperit cel mai important secret dintre toate: să nu își facă rău.
Ieșeam în curte, în noțile de vară, și mă uitam înspre lumina roșie a lui Marte și spuneam ”Ia-mă acasă!”, scria Ray Bradbury, în Take Me Home.
Weekendul ăsta, ne uităm și noi spre cer și apoi, înapoi, spre Pământ. Poate călătoria ne va vindeca puțin resemnarea și ne va aduce aminte că plutim într-un Univers infinit, care ne rămâne de descoperit.
