I'm reminded of a song that says "parents just don't understand", that's the point of parents Aussie_angel5, to not get what you do or why.

Plus otaku doesn't mean anime fan just fan so they hate music otaku, fashion otaku, "whatever" otaku because of the feeling of wastefulness (life, time, ect.)
Some people believe that if you're a fan/fanatic of something, you will loose your time on said thing (whatever it is).
