Harry Potter/Heartwarming

J. K. Rowling's characters might talk about the great power of love, but her examples speak louder than words.

Books

 * See Harry Potter (novel)/Heartwarming.

Films

 * See Harry Potter (film)/Heartwarming.

Others

 * A letter from Alan Rickman. We thank you too, Jo.
 * An announcement from JK on YouTube. Also doubles as a Crowning Moment of Awesome, as she plans on revealing info she's been hiding for years.
 * Meta-example, a bit heartbreaking now; "When I’m 80 years old and sitting in my rocking chair, I’ll be reading Harry Potter. And my family will say to me, “After all this time?” And I will say, “Always.”" — Alan Rickman
