I read the title to the the post here on HN. Then I read your comment, every bit of it, *except to the last line, when it finally hit me I was probably misreading the text and it said nose, not noise. This is all on top of me having had the same problem a week or two when this was reported here then. It's crazy how much of reading is whole word pattern recognition using context, and how weird it can get when it fails.
