I was going to reply before, when I knew what I was going to say, but then I realized I didn't know what I had to say. So I'm replying now in order to say that while I was going to say something, I didn't know what it was, and so I didn't reply. At that particular moment.

*rereads the chapter in order to try to remember what it was that he was going to say*

...Nope, still lost it. Good chappie, though.
