Don't really care if they're 12 or 20 or whatever.... that's one way youngsters learn - when someone calls their ass on the carpet for such nonsense. Its not only childish, its unmanly
Besides... we're talking about a Shinto goddess who's effectively been around for hundreds of years. That almost moves their ranting from poor manners to delusionary
especially when she flat out says there was someone she liked early in the story.
Meh.... this is one of the reasons I tell Americans to think really hard before calling themselves "otaku".
