I have a couple of party tricks that I like to pull out from time to time. One of them is reciting the Greek alphabet, which I memorized in 6th grade for extra credit and have never managed to forget. Another is being able to list all 50 states in alphabetical order (according to the Latin one, not the Greek one). Lastly, I am fairly accurate at guessing people’s Hogwarts House, and can usually judge where a person belongs within a few days of knowing them.
For those who might not be aware, Hogwarts is a fictional boarding school for witches and wizards within the Harry Potter universe.
