I didn't even mean to its was hilarious

SO TODAY IN ALGEBRA WE HAD A PROBLEM ON THE BOARD AND I THOUGHT THE TEACHER MESSED UP ON THE ADDITION. BUT WHEN EVER WE CORRECT HER SHE GIVES US CANDY. I ALREADY CORRECTED HER SO BEING A GOOD PERSON I LET MY FRIEND TELL THE TEACHER SHE MADE A MISTAKE BUT I DIDN'T PUT A ZERO ON A 3600 AND HE GOT EMBARRASSED IN FRONT OF EVERYONE
