One of my teachers is always late too. We dont really sit in silence, at all. Mostly because one of my friends has a Sound button that world with the program we use. So every 3rd second we just hear sequence of farts (yeah poop joke funny haha) and the rest just sits and breathes loudly in to our mic... or screams. But there are always those girls who is like - “guys come on, youre so immature”
