Sometime between seventh and eighth grade I stumbled upon a story which stuck with me, even though I forgot the title and the author.
As far as I can remember, the story went that this astronaut/colonist lives on an asteroid (maybe he was stranded there) along with a robot to assist him. The astronaut dies knowing of his solitude and the robot sort of takes him in his arms, consoling him either by singing or by putting out punched paper.
My guess is, this story was written in the 50's/60's by a prominent author (since it appeared in my Italian middle-school anthology).
