They do say 'What's wrong, Omi?', don't they? And he just says, 'Oh, sorry, it's nothing' and everyone goes on with life as if it didn't happen. ^^;; If my friend had done that, I'd be kinda concerned...

But then, I guess there isn't much they can do if he says it's nothing. And... well... they're *all* in need of conselling, I guess...
