The Lord of the Rings. It has become such a big part of my cultural self. I love everything about it, but especially the fact that there is an entire universe Tolkien created, mainly because of his love for languages. That kind of passion is absolutely amazing and it kind of taught me that it's good to be passionate about something. It also taught me that some thing "nerdy" is actually very widely accepted to be one of the greatest works ever written (and one of the greatest films), and in turn it led me to accept that you shouldn't be ashamed of the thing you like, even if they are nerdy/geeky/dumb or stupid in other people's opinion. It also got me super interested into world building, which I'm expressing currently in building a boardgame.
Favourite part is hard, but the Ride of the Rohirrim gives me goosebumps everytime someone even mentiones it.
At a club, I just asked her "Wanna make out?" and we did. Very weird that worked.
