For me, it may be that the toilet paper roll needs to have the open end away from the wall. I don’t want to reach under the roll to take a piece! That’s ludicrous!
That or my recent addiction to correcting people when they use “less” when they should use “fewer”
Why use any of those options and not just a number; “three days from now” etc.? Because the flow of language can feel better or more natural using some words over others. You can also notice that the way people interpret it can change based on where in the week it is. On a Monday, “this” and “next” can have the same meaning but not on Friday.
My argument is simply that “this” and “next” should be synonymous under this context since they mean effectively the same thing by that usage. It also would mean that it won’t change depending on the point in time of reference.
