Tomorrow is Halloween, which we all know is a bittersweet day in Harry Potter's life. On that very day in 1981, the first wizarding war ended, Harry got his iconic lightning scar by surviving the killing curse, and Voldemort killed his parents. Based on his history with the holiday, I'm pretty certain Harry wasn't looking forward to trick-or-treating and candy corn when October rolled around every year. It's a good thing dressing up for Halloween isn't as much of a thing in the UK because if it was, I could imagine that Colin Creevey might've dressed up like him before getting to Hogwarts. After all, he's apparently the most famous child in all the wizarding world. If there weren't Halloween costumes of a baby with a giant scar on his forehead, some wizard costume maker was missing out on a lucrative money-making venture. If you are ready to celebrate Halloween the Harry Potter way, these Harry Potter memes are for you.
