I didn’t dislike this short story but I don’t think it was my kind of thing as I very rarely read sci-fi. I found the ending incredibly predictable but that may just be because the plot has become so commonly used and at the time this was written, it would have been more original. 

I also didn’t think the way the sign changed when the character came back made any sense. The fact that the spelling changed but not the words, individual letters or grammar seemed unrealistic.

Overall, if you like sci-fi I would definitely recommend this short story.
