I don't think my parents say anything. Although my brothers sometimes make fun of me and day why are you watching pokemon or Yu Gi Oh which are quite known for being childrens shows well over here anyway. But if anyone says its for kids I think I will shut them up.
Also even if it was for kids I wouldn't care I mean if you like it watch it end of story.
My mom praised me for watching anime once... she said "Oh, I didn't know there was a romance anime"... I later told her that the anime was called School Days and told her about the ending 8D she probably wont say anything good about anime again
My parents are mixed about it. ;o My mom is all whatever about it but still supports me. Though my dad thinks it's nonsense. I guess he just wont get it? But they are both fine with me watching it as long as i dont fail my classes or spend unnecessary money on it.
My mom said I need to grow up and stop watching cartoons... parents dont get it lol.
*Realizes you are not around, but why waste a good topic*
I would ask them to sit down and watch an anime with you. Just be careful of what you pick though.. Maybe, pick one with a deep plot story like Air TV, Kanon, and/or Clannad ^^ Something, with a meaning that you have to think about that may not jump out at you right away ^^
If you really want to prove to them that anime goes beyond being your typical cartoon, show them Elfen Lied or Here and Now, There and Then (did I say ti right?) ^^
My parents always call anime cartoon~ But I dont mind, it's not like they are interfering with me. And to be honest I read manga rather than watch anime. My brothers however only watch anime. My parents basically know Death Note, Gundam and DB/DBZ/DBGT by heart(Because of my brothers).... Sometimes I watch Naruto with my mom. I think she secretly likes it *shrugs* so all is well = D
I remember when my brother played an episode of Elfen Lied on TV... Mom was shocked xDDD
