If I were a teacher at Hogwarts I would give and take points a lot, but I wouldn’t use multiples of 5.
“Thank you for your answer Emma. 3.76 points to Hufflepuff.”
“But professor, you can’t do that.”
“Shut up Ingo or I’ll take 45.00000001 points from Gryffindor.”
I found my blog from when I was 12 and this is the only good thing on it
