Again the changes are few. I'm not at all sure I can get away the line, "A wall stands up for me." I like it and I think it's too clever and it fails by its cleverness but there's something appealing about its failure. Could be it's out of place.
I returned line breaks to the piece and the banal dialog was painfully exposed. The dialog works best, if it works well, in a doesn't-matter-who-says-it sort of way. I like the naturalness of it -- sounds like real people talking -- but this is a tiny universe and the things in this universe are huge because there are so few things in this universe. Reading it the umpteenth time I think it works. This way. As a prose paragraph. Read in a rush, without the concentration of attention line breaks invite.
