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”
I prefer the TP to unroll off the top, but it may be necessary to reverse it if you have a cat that enjoys unrolling the entire thing.
