Dad: he's a BIG Harry Potter fan, and he was the one I would go to for discussing theories
There's also a comic we both share a big fondness for.
Anime-wise, he did develop a mild interest on Full Metal Alchemist, and watched a fair amount of the old series.
Mom: her interests are as far away of TV, books and movies as you can imagine. I have technically no common interest with mom.
Except for a mild interest of her for Harry Potter (Which she introduced me to, after all)
Sis: we have MANY likings in common. Singers, HP, many animes&mangas, Disney, Tales of, etc etc etc
But...not really fandoms? Sis isn't a fandom person, she doesn't interact with other fans. She carries on with her fanaticism on her own.
Besides, our strongest interests don't seem to coincide. Like, she was never as much of a FMA fan as I was.
And she just can't find herself to care about Hetalia. A pity; I'd like someone to share my stuff with.
As for me, I'm not into any of her favorite series.
I am a lonely fangirl in my family xD
It's fine, really. My sister is more a fan of teen pop music people... do not want XD
Eugh >.< Fortunately for me, my sis isn't a fan of those 8D;
XDDDD Lucky you, trust me!
We actually own the Justin Bieber movie on DVD. Ew.
