Harry Potter and the Philosopher Stone is a book written by J.K Rowling. At his 11th birthday, harry discovers he is a wizard and that the death of his parents wasn´t a fatal car accident but the wizard Lord Voldemort kills them. He gets sent to Hogwarts, a school specialized for witchcraft and wizardry were he meets his friends Ron Weasley and Hermione Granger. While still trying to get adapted to his new life and friends, he discovers many secrets including the philosopher´s stone whom he prevents Lord Voldemort from obtaining. There´s this quote:
“´There are all kinds of courage, ´” said Dumbledore, smiling. “It takes a great deal of bravery to stand up to our enemies, but just as much to stand up to our friends. I therefore award ten points to Mr. Neville Longbottom.”
On this quote, Dumbledore (Hogwarts principal) awards Neville (one of Harry´s friends) because he tried to protect him when finding out Harry was about to do something risky. I personally really liked that quote because it shows that true friendship does exist and that if you really care about your friend and he/she is about to do something wrong, it is better to stand up to them and make them reason other than later regretting not saying it.
