grow the fuck up.
A South Korean naval ship sinks, possibly due to having been torpedoed (by North Korea, no less), and all people can think about on omonatheydidnt is how long their favourite music shows have been cancelled.
I don't think there's a word for this. And I don't think you need to be Korean to imagine how horrible the news must sound, nor do I think anyone has to sound overly sympathetic in order to sympathise. But I don't see what's so hard about finding something else to do while the shows are being cancelled.
It's not like it's just a quarter of the members commenting on the posts who're bitching about the cancellation of the shows, it's more than half.
When exactly did Omona get taken over by a bunch of five-year-olds?
