We were doing a reading comprehension when suddenly a student leapt up and ran out screaming.
Now, my classes are not usually that exciting.
What had happened was, she was sitting next to a girl who is a bit of a skivver. Let's call her Girl A and the screamer Girl B.
Girl A was using the class time to discreetly fool around on the Internet. Specifically, to fool around on an Arabic website that purports to tell you the future (terribly haram in the Islamic world, BTW).
Girl A had typed in a silly question to which the website bot replied "Stop playing! This is not a time for playing!"
Which caused a bit of a sensation. Especially with Girl B, who is a fairly sensitive soul.
