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”
The “is a hot dog a sandwich” and similar discussions are solved with the mighty sword of language and not some rigid taxonomy about fillings and bread.
Imagine a set of food items on a table, hot dog amongst them, but not other pseudo-sandwiches. I ask you to “Please pass me that sandwich.” If there is but a moment’s pause in your mind before you reach for the hot dog, even if it’s as you surmise I must be speaking about the hot dog as there are no other sandwich-like items available, then it is not a sandwich.
