My parents never understood my nerd activities. They thought my anime-love was downright weird. They continue to think most things I like are weird. Sometimes, I wonder if I was born into the wrong family. I no longer live with my parents, so... it's not a problem. I just think it's kind of sad to be on the phone with my mother saying "Bob and I went to a local Renaisance Faire today" and to have mom say "Now, you see, I think that's dumb."
I tend to be careful about explaining my anime hobby to fellow adults, if I speak of it at all. It can actually even be more awkward than the bone-art thing I do.
Speaking of that, I think I actually scared off a therapist when I showed her my painted horse skull - I'm proud of that thing. So, another thing that is not well-understood.
Fan fiction isn't well-understood or liked by all, either, even online. I think it's the only hobby that I have as an online-thing that OTHER ONLINE PEOPLE don't always accept. I've gotten into FIGHTS - even here! At this board! Over the "legitimacy" of fan fiction as a hobby. --- Oh, and yes, I write original stuff! Click my sig to get one of my novels. I do fan fiction because it's fun for me. I'll defend my fun to the death.
