Dear headmistress.
Cause now your the headmistress. You asked me about my school years, and you wanted some answers. Why I didn't ask questions in class? Why I did my homework at night? Why I didn't came to you when I needed help?
To answer all of the questions I'm going to show you my schedule before Hogwarts:
-Waking up at like 06.00. Not a minute after.
-Make breakfast in 15 minutes. If not I would get a slap or two.
-Do chores. I couldn't ask them to show me how to do it. I learnt it all by myself. If I wasn't finished by the time they came home I wouldn't get meals that day, or get locked in my cupboard for the rest of the day.
-Never take food from my relatives. Never ask questions. Never be seen by important people... This rules had been following me for the past years.
-Go to bed after all the meals was finished, and all clothes and dirty things was clean.
-Homework was done in the cupboard. Wasn't done until 02.00.
-The same all over again.
If you still have questions about my school years, then you haven't read the whole answer.
Sincerely
Harry Potter
