I decided to try it on my classmate Kylie. I really needed an eraser but she was known of being quite selfish with her stuff, so I asked, "May I borrow your question paper?" She looked at me passively and continued working on her exam. Then I asked, "May I borrow your pen?". "Don't you have eyes to see that I am using it?" She snapped. "Fine then, may I borrow your rubber," I finally asked.
