GUYS LAST WEEK my teacher said to RAISE YOUR HAND if you understand something and I didnt understand so I didnt raise my hand and he was like "oMg I dOnT sEe A hAnD uP" and BLAMED IT ON MY CAMERA ANGLE. So then he asks me to do this problem involving it, and of course I got it wrong. THEN he was like "I tHoUgHt I sAw A hAnD uP tHo" EVEN THOUGH HE LEGIT MADE ME PUT IT UP!!!
