My school uniform: Khakis, Polo shirts, belt. But everything has to be from a certain manufacturer. And on Tuesdays we wear a shirt with the school logo, which has to be white. And on Thursdays we must wear a blazer, tie, and button-down shirt. Girls don't have to wear ties on Thursdays, but must wear plaid skirts. The skirts must go down to at least their fingertips. We get detention if we forget our belt, don't tuck in our shirts, etc.
I think the most annoying thing about people trying to sneakily use a phone is that it is impossible to do.
You end up sat there, looking down at your lap, with your hands under your table, with a faint glow beaming up at your face.
Either you're obviously using your phone, or you're jerking off your fluorescent rooster.
There's no wonder it annoys teachers. It's just unbelievably rude to think you can so obviously ignore a class and then manage to lie about using your phone.
Today, my friend masturbated and touched my hand. I whispered to him that my hand smelled like his richard. The teacher heard me. FML
Edit: ^^ That's not a joke that actually happened.
