Well, here's the proof - it's the Reck Family sporting their Hogwarts House Spirit Shirts.
I can't wait to get to Universal Studios Orlando because I am SO READY to explore the Harry Potter world there. I'll be honest, I originally conceived of these shirts as I planned an imaginary trip for us. (Did I mention I also plan imaginary trips? No? Oh - that's one of my "things." It's cheaper than therapy, you know.) I'm happy because now people who are actually going to Universal (like, in real life) buy my House Spirit shirts.
So do people who are proud of their true nature, be it Slytherin, Gryffindor, Ravenclaw or Hufflepuff. What's your house? If you think you're a particular house but haven't taken the quiz on J.K.'s official (Harry Potter) site, I recommend you do that before you answer my question. You might be surprised! (My daughter and I sure were.)
