Even though it was quick, it was fun! I love codes and things like that! I also like languages -- maybe that's why.
By the way, here is a brief record of my insanity:
1) Decoded Gnomish script written alongside the bottom of the first Artemis Fowl book.
2) Taught myself Atlantean from Disney's Atlantis.
3) Taught myself Drwarvish runes from Lord of the Rings. Also tried teaching myself Elvish.
Did I mention I like puzzles as well? That's probably why I'm loving Sherlock so much~!
