"At night, there was the feeling that we had come home, feeling no longer alone, waking in the night to find the other one there, and not gone away; all other things were unreal. We slept when we were tired and if we woke the other one woke too so one was not alone. Often a man wishes to be alone and a woman wishes to be alone too and if they love each other they are jealous of that in each other, but I can truly say we never felt that. We could feel alone when we were together, alone against the others. We were never lonely and never afraid when we were together."
Hemmingway’s A Farewell to Arms
