Odd and Mauve have pretty similar hobbies; If they're outside, they like to take long walks and find good places for sight-seeing or people watching. And once they're inside, they like to think of something that caught their attention during their time out (be it a landmark, a kind of shop they haven't seen, or just a bit of information they overheard) and look deeper into that subject, talking about their findings together and what they both think about the topic at hand
