The only place Harry really ever had friends. A school for magical people just like him. A place where all the teachers care about SOMEONE, even though they may not show it. Somewhere that lives get risked and lives get saved at the same time. Somehow, everyone fits in one or more ways. Where many people started the path to becoming famous, and others infamous. How Harry Potter became the wizard we all know (but maybe not love) In shorter words, home.
At the Quidditch World Cup
Harry: I can't wait to go to Hogwarts next week!
Hermione: Harry, we go to Hogwarts in three weeks...
