Snape: Potter, did you finish your homework? It's due tomorrow.
Harry: uh no not yet, sir I'm almost done
Snape: Well I asked young Weasley boy and he said he didn't either, so if you two don't finish it soon, Gryffindor loses twenty points and detention for you both. And also use grammar, punctuation, and capitalisation.
Harry: your mean it's just it's hard!
Snape: Too bad, Potter! You better finish it. If you don't do it, you better prepare for trouble.
