I have to brace myself whenever I watch Deathly Hallows Pt. 1. Both at the beginning, and the end. Even though I read the book, so I'd be a little prepared, the book only has Hermione mentioning wiping her parent's memories. When they were actually showing it in the movie, it really hit me. She's erasing her entire life, like she never existed. (And of course, while I'm trying to to start bawling in the middle of the theater, my mom, who didn't read the books, wants to know why Hermione is using her wand on her parents). Then, of course, at the end when Dobby dies. Out of all the characters that died, his hit me the hardest for some reason.
