I'm in my 40's with a 13 yr. Old who absolutely loves it. She loves shopping at Hot Topic and enjoys checking out Manga's or buying them. She has recently talked to me about Cosplaying and going to comiccons and animecons. I also watch them with her, and she love's quizzing me! So far she's been watching Black Butler, Attack of the Titans, Our an High School Host Club, Blue Exorcist, Bleach, Durarara, Fairy Tale, Full Metal Alchemist and very recently, One Punch Man.
She started playing violin last year and before that, and even now, loves video games. I think it's actually helped her socially, because she's not into sports or cheer leading or trying to be "popular" like many of her peers (middle school...yay!). She's found a like minded group of teen girls and boys who are into the same thing, and now she has something in common with her peers. She got picked for robotics this year, which I think because anime brought out her creative side, and she loves that they can create something.
She is learning to love classical music and jazz music because of the awesome soundtracks, and she practices her violin harder because she wants to be able to play like those musicians
Somehow, she discovered the Hamilton Soundtrack and has most of the songs memorized and wants to see it when it starts touring!
