For the longest time, and still a bit now, I considered myself a "closet otaku" because I don't really outwardly express my love (obsession?) for anime and manga. Most people I talk to are surprised when they hear I like anime/manga, though I'm not really sure why because it's not like I actively hide it either. I just don't talk about it if it isn't relevant to the conversation.
I'm somewhat involved in athletics, seeing as I'm working as a personal trainer, but I was also heavily involved in the performing arts throughout school because actors and dancers are the people that I want to train in the future. Specifically, I want to train musical theatre performers, but I certainly still enjoy training the average Joe. I feel that this range of interests is why people are often surprised about my otaku-ess. However, I quickly gained the title "the nerdy trainer" at work, and I guess people talk about it because employees from other departments now approach me to talk about anime. Maybe I have fully emerged from my otaku closet?
Anyway, I'm trying to be more open about the things I like, such as wearing items that are representative of my favorite shows and such. It still feels weird, but thankfully the people I've encountered while displaying my fandoms get excited and we talk about fun things. c:
I recently took part in my first anime convention (Daishocon), and it was super fun and I'm exceedingly excited to do it again! This year (2016) I am going to be leading a panel at Daisho about basic fitness stuff to help members of our sedentary fandom lead healthier lives.
