You ever notice that’s usually what people say when they have absolutely no intention of returning that piece of paper. Some of the language we use is really quite comical, or at the very least often inaccurate.
When you ask someone to borrow a piece of paper or to borrow a pencil, you’re not going to return those things. Don’t ask to borrow! What you really mean is, “Can I have..?”
On some subconscious level, as humans we’d prefer to lie to one another and fake politeness, rather than be straight forward. Perhaps I’m just a little too upset about this.
