I'll be truthful and say that once I realised what the background was behind this short story I very nearly stopped reading, if only because it's a trope I've come across before and it doesn't usually work for me. However, @Headstall managed to grab my attention early on and hold onto it until the end.
Two lost souls come together one evening. Trent is willing to take a chance, but Armie is reluctant as he feels it can't work. As the pair talk, and I learnt more about what has brought each of them to this point in their lives, I found myself liking each of them more and more.
I'm not usually one to give spoilers in story comments so, if you want to find out whether Arnie's walls finally crumble (to use the metaphor that @Headstall uses in the story synopsis), you'll just have to read the story for yourself. I think you will enjoy it.
