Just so that you are aware, I'm starting this story from when Harry is in the 3rd year.
Harry, Ron and Hermione ran to Hagrid's, robes billowing behind them. Once again, on the way to their class they had been held up. Snape had caught them complaining about him…
"Stupid Sod," said Ron darkly "researching that many potions is going to take me all year!"
"Well it serves you right for flicking frog brains at each other – don't you give me that look, you lost Gryffindor 50 points Harry." Hermione added, eyeing the look Harry had on his face.
"Bet that slimy git will bring the due date back so that we only have a night to do it – and I have quidditch practice tonight as well!" said Harry, slamming the helmet down upon a wheezing suit of armour as they made their way though the great hall.
"Right you are Potter, you don't seem to need a week for that essay." Snape sneered as he went past "Oh, and 10 points from Gryffindor for damage to school property." He pointed to the suit of armour that Harry had so brutally slammed down.
"But sir – he didn't damage i-" Hermione started in a suppressed rage
"Silence Miss Granger! You will not speak until spoken to, 5 points for speaking out of line! Now – get to class."
Hermione struggled to hold both Ron and Harry back
"Just ignore it, IGNORE IT."
"Stupid git."
"Smash his face in..."
"Talking out of line my ass…"
"We better get to class, we are already 10 minutes late." Said Hermione looking at her watch…
"Finally you three are here! I was startin' to wonder where you were!"
