Science is awesome, pass it on
The moment you discover that there is a law in all schools if the teacher does not appear in the first 15 minutes of class, you can leave the class.
THE WORLD MUST KNOW.
GET THE WORD OUT, GUYS.
and i did this every time my teachers did not appear.
I tried this a lot of times and my teachers always say «I don’t care! i am here now!» what on earth? -.-
