@Natasha_Jay It's the little channels of blank beige, like old (inappropriate) tape adhesive that's gotten covered by dust over the years, around each exposed "cable" that kills me.

If this was my actual carpet, I can guarantee you that the "empty" spots between the cables would wear thin within like a year, as there are only so many places to put my foot down without possibly stepping on a cable or picking one up on my foot on the next step.
