I don't have any hobbies. You know, I'm very embarrassed when people ask me what are my hobbies; I don't have any hobbies. I mean, it's just enough to keep up with the things I'm trying to solve.
I could put a sudoku at the end of every chapter and you'd have to solve it to progress through the story, but that doesn't address what would make people want to interact.
I grew up pretty peacefully, in that Eastern way. You easily solve problems, believe in harmony. Reduce conflicts, take orders until one day you give orders.
