It's okaii. I usually find little mistakes in my stories too when I am going through them. But then I am too tired to care and just can't be bothered to fix them.
This chapter was admirable, it truly was a touching thing to read. In fact this whole story has just been full of sad realisations that just because things get better for a moment, doesn't mean they'll stay that way. Well, that's what I think anyways. There's probably a lot more to it but I couldn't begin to explain it all in the state I am in at this moment(I literally feel like a zombie come back from the dead.) But you should know that this story is something I will probably never forget.
